It is compared with conventional doping-less TFET（DLTFET） and dual material gate doping-less TFET（DMG_DLTFET） on the basis of analog and RF performance. The HD_DMG_DLTFET provides better ON state current（I_（ON） =94 μA/ μm）, I_（ON）/I_（OFF）（≈1.36×10^（13））, point（≈3 mV/dec） and average subthreshold slope（AV-SSD40.40 mV/dec）. The proposed device offers low total gate capacitance（C_（gg）/ along with higher drive current. However, with a better transconductance（g_m） and cut-off frequency（f_T）, the HD_DMG_DLTFET can be a good candidate for RF circuitry. The early voltage（V_（EA）/ and output conductance（gd/ are also moderate for the proposed device with comparison to other devices and therefore can be a candidate for analog devices.From all these simulation results and their study, it is observed that HD_DMG_DLTFET has improved analog/RF performance compared to DLTFET and DMG_DLTFET.展开更多

The paper compares the device performance of the conventional doping-less TFET （DLTFET） and doped TFET （DGTFET）. DEDLTEFT gives the superior results with high ON state current （/ON - 0.56 mA/um）, ION/IoFv ratio - 9.12 ×1013 and an average subthreshold swing （AV-SS -- 48 mV/dec）. The variation of different device parameters such as channel length, gate oxide material, gate oxide thickness, silicon thickness, gate work function and temperature variation are done and compared with DLTFET and DGTFET. Through the extensive analysis it is found that DEDLTFET shows the better performance than the other two devices, which gives the indication for an excellent future in low power applications.展开更多
