Hello! we know that it’s a remarkable fact that silicon has been a corner stone of computing for many decades in the constantly progressing world of technology. Computer chips starting with the first transistor up to the most modern smart phones have always made use of silicon.
This fact, however, is through striving to which silicon is capable of, researchers and engineers are now looking out for new materials and technologies that have the potential to transform computing. Here, in this blog/review, we will attempt to understand why silicon might be at the end of its tether, the possible successors, and what such developments imply.
The Silicon Era: A Short Profile
Silicon has been the main material that has been used in electronics since 1960’s. The attractive characteristics of silicon in particular have waned it to become the material of choice in the production of semiconductors that drives today’s electronics. Silicon is plentiful, inexpensive and the electrical properties of silicon have been very well characterized and are well suited for many uses.

Despite its enormous success, the silicon chip, or integrated circuits have been the forte of computing, making electronic devices shrink and perform at their best. The Moore’s law has been named after the Intel co-founder Gordon Moore and it has stated that the number of transistors on a chip would double about every two years resulting into the increases in the performance and the reduction in the costs. In this prediction, the future was formed for decades, and that led to the development of technological progress.
But the problem is that silicon has certain drawbacks which has been making its presence more and more felt in recent years. With increasing size of miniaturization, problems like heating effects, power dissipation and crosstalk we are now encountering. It is for these reasons that the industry needs to look for new materials and technologies that could enable it to continue with its progression.
The Limits of Silicon
Miniaturization Challenges: If the size of the transistor drops to nanometers, quantum effects kick in, problem such as leakage curent and other reliability problems emerge. That is why one can say that the physical limitation of the silicon material has made it to reach a state where Moore’s law is almost expiring and the attempts to shrink the features further may not increase the performance.
Heat Dissipation
This is because as transistor sizes are reduced their power densities increase and hence generate high heat. Crisp cooling is a requirement, however it makes design and expenses more complicated.
Power Consumption
They also stated that as the number of transistors goes up the power consumption also goes up. Power regulation becomes a complex process, which may result in a reduction of the devices’ speed and their battery utilization.
Interconnect Limits
The connection between the transistors referred to as the interconnects also suffers from scaling. Since the size of transistors keeps on reducing, the distance between them also reduces but this causes increased resistance and capacitance of the interconnect path which reduces the performance.
Emerging Alternatives to Silicon
In order to combat the aforementioned challenges, authors are looking for different types of other materials and technologies. Here are some of the most promising candidates:Here are some of the most promising candidates:
- Graphene: A single layer of carbon atoms bonded hexagonally is called graphene; it is an excellent conductor of electricity and heat and has great mechanical strength. Graphene might replace silicon in certain so that better speeds and less energy consumption are some of the possibilities. Nevertheless, 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 cylinder form have electrical properties that have potential in surpassing silicon. They can be utilised to fabricate transistors that possess higher efficiency, hence occupying less space. Although encouraging, some issues still exist for the use of carbon nanitubes both in large scale production of semiconductor electronics and in the successful integration of it into the technology.
- Transition Metal Dichalcogenides (TMDs): Some of these materials are molybdenum disulfide for example, and these are materials that have features which could be beneficial in the development of future electronics if employed there. Thus, they possess tuning controllable bandgap and they have made a wider usage field from low power electronics to the flexible displays.
- Quantum Dots: Quantum dots can be described as nanoscopic point like structures that display quantum behavior. They can be utilized in many things from displays to other applications in biology imaging. Quantum dots may have implications for computing, specifically to develop new technological structures to create types of memory and logic devices.
- Topological Insulators: While in their bulk they possess insulating properties, they also have the capability to conduct electricity on their surface. They could potentially result in new kinds of electronic devices with novel characteristics which could in future advance field such as spintronics and quantum computing.
- Beyond Materials: New computing paradigms are shifting the work paradigm as a whole in general from conventional to unconventional ways. Apart from this, researchers are conducting profound studies on new material and other computing architectures that may be considered as the future of technology.
- Quantum Computing: Quantum computers employ quantum bits -or qubits-being capable of performing calculations that cannot be done by a conventional computers. These get the potential to solve multi dimensional problems, in particular in the areas of cryptography and material sciences etc. However, there are still much still in the experimentation stage, but due to progresses made in quantum computing many fields could change.
- Neuromorphic Computing: Neuromorphic computing, as the process of designing circuits resembling neural structures of the human brain, is called. It could therefore result in enhanced and effective artificial intelligence structures for instance in Robotics, Natural language processing, and cognitive computer.
- Optical Computing: Optical computing employs light as opposed to electrical signals in order to accomplish computations. This approach could thus result in development of computers that are faster and at the same time consume less energy as optical signals require less energy to convey information as compared to electrical signals.
- DNA Computing: In DNA computing, use of DNA molecules as processing elements is made for the performance of such computations. To be sure, as of now the primary application is still mostly theoretical but it holds the promise of being capable of solving specific kinds of issues faster as compared to a traditional computer.
