Silicon has continued as a major element in computing for many decades in this continually evolving world of technology.
If researchers are pushing silicon to its limits, the attempts of engineers are no less: they are seeking new materials and technologies in the hope of modifying computing itself.
Here in this blog we would try and find out the reasons why silicon may be nearing the end of its tether, the possible successors, and what such developments mean.
Silicon Era: A Brief Overview
Silicon, the main among the charges from above, has been the only one used for electronics from the last 1960’s. Beautifully silica possesses the qualities that made it the obvious choice for semiconductors that fuel today’s exciting new electronics. Silicon is most abundant and cheap while the electric properties have been mapped very well and respond to many applications.
Although it has enjoyed stellar success, one cannot forget that silicon chips, or integrated circuits, have drawn all along computing making devices get miniaturized and most efficiently performing. The Moore’s law stands for the Intel co-founder Gordon Moore, stipulates mostly that the number of transistors placed onto a chip will double about every 2 years and produce increases in performance and decreases in expense. That really framed the future for decades to come in shaping itself for decades, which drove the development of technological progress.
With miniaturization that increases, silicon has thus developed limitations that are more pronounced today. Problems such as heating effects, power dissipation, and crosstalk are now the issues that we are facing. In these considerations, one can therefore understand why the industry has to seek new materials and technologies for carrying on in its advancements.
Limits of Silicon
Challenges of Miniaturization: At the nanometer size of a transistor, quantum phenomena start dominating, leading to leakage currents and several other reliability issues. This is the reason why one could say that because of the physical limitations of the silicon material, the Moore’s Law has come very close to terminating and any further attempts to miniaturize the features will not enhance performance.
Heat Dissipation
The reason is that as small transistors grow, the power density explodes and so does the heat. Crisp cooling is a necessity but complicates the design and increases costs.
Power Utilization
Then, they also expressed that with the increase in one count of transistors, power consumption also occurs. The power regulation will be thus become more complex and this will in turn affect the speed of the devices and the battery usage.
Interconnect Restrictions
Interconnect is a term that defines a connection between transistors as a barrier to scaling. The distance between transistors decreases owing to the continuous decrease size of transistors, but this decreased distance contributes highly to increased resistance and capacitance of the interconnect path which consequently reduces the performance.
Emerging Alternatives to Silicon
To counter these challenges, the authors are already searching for other alternative types of materials and technologies. Here are some of the most promising candidates:Here are some of the most promising candidates:
Graphene
A single layer of a carbon atom bonded hexagonally is called graphene; it is one of the excellent conductors of electricity and heat and mechanical strength. Graphene would then finally replace silicon in a few things so that better speeds and less energy consumption would be amid a few of its possibilities. It should be remembered, however, that the successful integration of graphene into existing semiconductor processes can still be regarded as a work in progress.
Carbon Nanotubes
These structures of carbon atoms in cylindrical form have electrical properties that have a potential of surpassing silicon. Therefore, they can be used in fabricating transistors, which can be more efficient and would occupy less space. However, several problems still remain for the application of carbon nanotubes in the large-scale production of semiconductor electronics and in the successful integration of this technology.
Transition Metal Dichalcogenides (TMDs)
Some examples of these materials include molybdenum disulfide, and these are materials having some characteristics that can be useful in future electronic development when used therein. Thus, they have controllable bandgap tuning, which has provided broader usage fields, from low power electronics to flexible displays.
Quantum Dots
Quantum dots are essentially nanoscopic point-like structures whose behavior conforms to quantum postulates and can range from applications in displays to biology imaging. Quantum dots might have bearing on computing as new technology structures are being built up for various classes of memory and logic devices.
Topological Insulators
They have insulating properties in their bulk, yet have an ability to conduct electricity at their surface. These could lead to a new type of electronic devices with novel functions that could later advance field such as spintronics and quantum computing.
More Than Materials
New computing paradigms have largely shifted the work paradigm from traditional to unconventional ways as a whole. Apart from this, researchers are having penetrating research on new types of materials and other architectures of computing, which may be held as the future of technology.
Quantum Computing
Quantum computers use quantum bits or qubits and perform calculations that could not be made by a conventional computer. Such abilities have promising potential with respect to solving multi-dimensional problems, especially in the context of cryptography and materials sciences, etc. There are however much still experimental; however, progress in this field of quantum computing could make significant changes in many fields.
Neuromorphic Computing
Neuromorphic computing is a process of designing circuits whose structure resembles the structure of neural ones in the human brain. It can, therefore, lead to better and more efficient artificial intelligence structures for instance, in Robotics, natural language processing, and cognitive computer.
Optical computer
An optical computer is one that uses light signals to perform calculations rather than electrical signals. Hence, it can scale up to faster speeds while consuming less power, since it would require less energy to transfer information through an optical signal than by electrical means.
DNA Computing
It is a mode of computing that uses DNA molecules as processing units in order to execute a computational procedure. In fact, the application for these not being realized at present is still mostly theoretical, but it promises to infrequently perform such computation more quickly than a conventional computer would do.
Thus, there are the implications of the trends over everyday technologies:
They will enable real change in moving into new classes of materials, and new paradigms in computing will have transformative effects on most technologies, as seen by this report. Here are a couple of examples of areas where those advances could make change:Here are a couple of examples of areas where those advances could have changes.

Cost and Accessibility

Ethics and Security Issues

Concerns like how to manage data protection or security would withstand the ill and good sides of how such technologies can be misused and hence have to come upfront ready to be met by the right solutions.
Conclusion
Future chips will not be silicon, as researchers and engineers work on new materials and computing models to bring the chips to the next generation and new heights. This simplicity is not to diminish the great contributions silicon has made.
It is, however, diminishing now in its expert skill in scaling and in the provision of even more performance. Those alternative emerging trending and very innovative approaches discussed in the above blog post give a peep into a more enhanced future for computing.
