Transistor Manual Third Edition ECG-315 - VTDA - Germanium transistors | The Gear Page

refined versions of silicon began to supplant germanium as part of radio and television manufacturing.The performance of a tunnel field effect transistor (TFET) with a raised germanium (Ge) source region is investigated via 2-D device simulation with a tunneling model calibrated to experimental data. The comparison of various Ge-source TFET designs shows that a fully elevated Ge-source design provides for the steepest subthreshold swing and ...Mar 17,
