Query: Device Improvement and Circuit Performance Evaluation of complete SiGe
  Double Gate Tunnel FETs   In recent part extensive simulation work has already been done on TFETs.
However this is limited to device performance analysis. Evaluation of circuit
performance is a topic that is very little touched. This is due to the non
availability of compact models of Tunnel FETs in the commercial simulator. In
our paper for the first time we perform the circuit analysis of tunnel FETs
(extended channel TFETs), we test them over basic digital circuit. We generate
the TFET models by using the model editor in Orcad. Extensive circuit
simulation is then performed by using these models in the Pspice circuit
design. Performance of extended channel double gate TFET is evaluated on the
grounds of power and delay in inverter, nand gate, nor gate and ring
oscillator. Before that we perform device analysis of double gate extended
channel TFETs, extended channel has been tried before on SOI TFETs we try it
for the first time on double gate Si1-xGex TFETs. We even look at the effect of
introducing Si layer. The performance of this device is compared for different
Ge mole fraction and also with MOSFETs
