The p-i-n carbon nanotube (CNT) devices suffer from low ON/OFF current ratio and small saturation current. In this paper by band bending engineering, we improved the device performance of p-i-n CNT field effect transistors (CNTFET). A triple gate all around structure is proposed to manage the carrier transport along the channel. We called this structure multi-segment gate (MSG) CNTFET. Band to ...

the usage of turbochargers in diesel engines has led to the downsizing of the motors as well as usage of the waste gates in turbochargers. any dimensional reduction in turbochargers and appurtenant leads to an enhancement on the performance of internal combustion engines and in environmental problems in terms of aerodynamic, thermodynamic and mechanical specifications for both engines and turbo...

combined pet/ct scanners now play a major role in medicine for in vivo imaging in oncology, cardiology, neurology, and psychiatry. as the performance of a scanner depends not only on the scintillating material but also on the scanner design, with regards to the advent of newer scanners, there is a need to optimize acquisition protocols as well as to compare scanner performances on an objective ...

This study introduces a reversible optical fulladder. Also optical NOT and NOR gates are implemented through Electro-Absorption-Modulator / Photo Detector (EAM/PD) pairs, were utilized for fulfilling reversible R gate. Then, reversible fulladder was designed based on the proposed reversible optical R gate. The operation of the suggested fulladder was simulated using Optispice and it was fou...

High Q frequency reference devices are essential components in many Integrated circuits. This paper will focus on the Resonant Suspended Gate (RSG) MOSFET. The gate in this structure has been designed to resonate at 38.4MHz. The MOSFET in this device has a retrograde channel to achieve high output current. For this purpose, abrupt retrograde channel and Gaussian retrograde channels have bee...
