For exploring the origin for the interface states in MoS2 FET, the transient response of MOS capacitor to ultra-fast pulsed top gate voltage was studied with high time resolution current measurement system. The difference of time constant originated from trapping and detrapping of electrons on interface states was detected, which cannot be measured in C-V measurement.

This research presents a fabrication of triboelectric nanogenerator (TENG) using the sodium dodecyl sulfate (SDS)-functionalized carbon nanotube (CNT) / polydimethylsiloxane(PDMS) composites (SDS/CNT/PDMS) as a negative electrode and polyethylene terephthalate / indium tin oxide (PET/ITO) as a positive electrode. The effect of CNT concentration and the SDS concentration were on TENG performance were investigated. Experimental results indicate that the SDS/CNT/PDMS is an effective electrode to enhance the output voltage of TENG with a maximum voltage of 66.8 V enabled an approximately 6-fold improvement in voltage output compared to the pristine PDMS. CNT may help to the high conductivity and flexibility of CNT, resulting in fast charge transfer and fast shape-recovery, while SDS may help to increase charge density and furthermore CNT dispersion.

TCAD simulations have been performed to optimize well designed planar single-gate silicon (Si) vertical tunneling junction field effect transistor (VTFET) with average subthreshold swing (S.S.) less than 60 mV/dec for 0.3 V (=Vgs=Vds) operation. By scaling the equivalent oxide thickness (EOT) and increasing the gate-to-source overlap length Lov, it achieved both on-current (Ion) greater than 1.0 A/m and low average S.S. without pocket doping for forming tunnel junction in conventional VTFET.

Abstract In this paper, hot-carrier (HC) induced drastic off-state leakage current (Ioff) degradation for the LDMOS is found and the mechanism is also investigated in detail. Continuous on-state drain current flow of the LDMOS generates the HC which is trapped in the STI, and causes the drastic increase of the Ioff for the LDMOS. Therefore, HC induced drastic Ioff increase should be taken into account for the LDMOS design.

Using first-principles calculations based on density functional theory, electronic structure of domain boundary of MoS2 in which same polar edges are faced each other are investigated theoretically. We also find that the up-shift of energy bands at the domain boundaries are caused by charge accumulation. For such change in the energy bands, the defect levels at the domain boundaries play a decisive role.
