In order to obtain the electron transmittance and tunneling current, Airy- A nd exponential wavefunctions were utilized as analytical approaches. A transfer matrix method (TMM) was used as a numerical approach as a benchmark to find the best analytical approach in calculating the transmittance and tunneling current. It was shown that the Airy wavefunctions approach was a better analytical expression to calculate the transmittance and tunneling current. Furthermore, the tunneling currents computed under Airy wavefunction approach were compared to the measured ones to examine the model. It was shown that the calculated tunneling currents are fitted well by the measured ones. It was also shown that the model could be used in designing a high speed MOSFET with low tunneling current.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Anisotropic mass,Energy couplings,Gate stacks,Gate velocity,Tunneling current[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]anisotropic mass,energy coupling component,gate velocity,high-k dielectrick gate stack,Tunneling current[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ISESD.2017.8253342[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
