The analytical expression for quantum capacitance has been derived based on the normalized number of carriers/total charge density. The total charge density in the inverted channel is suppressed at large drain voltage but remains unaffected by introducing any new sub-band. Lowering the quantum capacitance in the CNTFET device is a major challenge to improve the performance of the device. Quantum capacitance takes lower value at higher sub-band when operated at low gate bias voltage. Lower quantum capacitance can be achieved for larger tube’s diameter due to reduced band gap and by controlling the BTBT (band-to-band tunneling) leakage current which is possible by choosing the proper dielectric material and gate oxide thickness. 2018-12-08T05:00:06Z 2018-12-08T05:00:06Z 2018-07 Article International Journal of Nanoelectronics and Materials, vol.11 (3), 2018, pages 249-262 1985-5761 (Printed) 1997-4434 (Online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/57585 http://ijneam.unimap.edu.my en Universiti Malaysia Perlis (UniMAP)
