Abstract
The exponential rise in the density of silicon CMOS transistors has now reached a limit and threatening to end the microelectronics revolution. To tackle this difficulty, group III–V compound semiconductors due to their outstanding electron transport properties and high mobility are very actively being researched as channel materials for future highly scaled CMOS devices. In this paper, we have studied a ballistic nanoscale MOSFET using simulation approach by replacing silicon in the channel by III-V compounds. The channel materials considered are silicon (Si), Gallium arsenide (GaAs), Indium arsenide (InAs), Indium Phosphide (InP) and Indium Antimonide (InSb). The device metrics considered at the nanometer scale are subthreshold swing, Drain induced barrier lowering, on and off current, carrier injection velocity and switching speed. These channel materials have been studied using various dielectric constants. It has been observed that Indium Antimonide (InSb) has higher on current, higher transconductance, idealistic subthreshold swing, higher output conductance, higher carrier injection velocity and comparable voltage gain compared to Silicon, thus, making InSb as a possible candidate to be used as channel material in future nanoscale devices.
期刊介绍:
We would like to inform you, that iJOE, the ''International Journal of Online Engineering'' will accept now also papers in the field of Biomedical Engineering and e-Health''. iJOE will therefore be published from January 2019 as the ''International Journal of Online and Biomedical Engineering''. The objective of the journal is to publish and discuss fundamentals, applications and experiences in the fields of Online Engineering (remote engineering, virtual instrumentation and online simulations, etc) and Biomedical Engineering/e-Health. The use of cyber-physical systems, virtual and remote controlled devices and remote laboratories are the directions for advanced teleworking/e-working environments. In general, online engineering is a future trend in engineering and science. Due to the growing complexity of engineering tasks, more and more specialized and expensive equipment as well as software tools and simulators, shortage of highly qualified staff, and the demands of globalization and collaboration activities, it become essential to utilize cyber cloud technologies to maximize the use of engineering resources. Online engineering is the way to address these issues. Considering these, one focus of the International Journal of Online and Biomedical Engineering is to provide a platform to publish fundamentals, applications and experiences in the field of Online Engineering, for example: Remote Engineering Internet of Things Cyber-physical Systems Digital Twins Industry 4.0 Virtual Instrumentation. An important application field of online engineering tools and principles are Biomedical Engineering / e-Health. Topics we are interested to publish are: Automation Technology for Medical Applications Big Data in Medicine Biomedical Devices Biosensors Biosignal Processing Clinical Informatics Computational Neuroscience Computer-Aided Surgery.
