Silicon complementary metal-oxide semiconductors or CMOS are important building blocks for various electrical engineering applications. These applications include fabrications for SRAMs, microprocessors, logic circuits, and microcontrollers, among others. A new study promises to improve their speed by 3 times, and energy efficiency by 4 times.
This new study is a result of work by researchers at Peking University and Xiangtan University in China. These researchers have come up with carbon nanotubes, which can replace CMOS in the near future. These new carbon tubes are as small as below 10 nm in size.
This study is particularly important to note for various engineers working with CMOS today. According to many experts in the electrical engineering field, the CMOS are expected to go out of applications soon. Moreover, these scientists predict that CMOS may be replaced as early as end of 2020. Hence, replacing new logic circuit boards, SRAMs, and microprocessor will be a considerable challenge soon.
Moreover, CMOS have been a cause of concern for various reasons. These are highly inefficient for their end-use. Furthermore, demand for entertainment, gaming, and video streaming continues to drive end-products like laptops. Moreover, the rising demand for energy-efficiency, and high-speeds for application like gaming will present new opportunities for companies working with current CMOS technology.
New Materials on the Horizon
These alternative new tubes provide immense hope for the future as application of carbon nanotube remains promising. The researchers also investigated other alternative materials like CNT. According to Lianmao Peng, CNT is also ideal for replacing CMOS as the traditional semiconductors can fail without notice. Moreover, these do not scale-down as required by next-gen applications like wearable devices. The nano-scaling requirement of new applications promise new gateways for materials like CNT in the near future.
According to the researchers, even with their limited lab-based fabrication capabiltiies, the new materials outperformed established materials by a significant margin.
