the performance of nanoscale field effect diodes as a function of the spacer length between two gates is investigated. our numerical results show that the ion/ioff ratio which is a significant parameter in digital application can be varied from 101 to 104 for s-fed as the spacer length between two gates increases whereas this ratio is approximately constant for m-fed. the high-frequency perform...

any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...

Using spice 9.3, we have modeled (I-V) characteristics of a Modified Field Effect Diode (M-FED) with gate length of 75 nm and oxide thickness of 10 nm. An SRAM cell (Register) has been designed with the simulated M-FED and has been compared to an SOIMOSFET based circuit. Simulation results demonstrate that clock frequency applied to a memory cell which is designed with M-FED is more than 2 orde...

Abstract The fabrication and I-V characteristics of the novel AlGaN/GaN field effect diode are reported. This diode has a distinguishing anode structure and the relatively thick AlGaN barrier layer in contrast a conventional field-effect Schottky barrier diode (FESBD). By using fluoride-based plasma treatment, we could reduce its turn-on voltage to 0 V and decrease its leakage current at the re...

introduction radiotherapy planning systems require many percentage depth dose (pdd) and profile measurements and there are various dosimeters that can be used to obtain these scans. as dose perturbation is particularly troublesome in smaller photon fields, using a low-perturbation, unshielded electron field diode (efd) in these fields is of interest. the aim of this work was to investigate the ...

in this investigation the effect of external field on the electron density of nanostructures of cds, cdse, cdte, gaas and polymeric structure of three, four, five and six units of cds as a kind of nanosolar cells has been studied theoretically. as modeling this system in nanodimension, molecular structures has used. specific properties of molecular structures permit us to consider different sym...

Introduction Radiotherapy planning systems require many percentage depth dose (PDD) and profile measurements and there are various dosimeters that can be used to obtain these scans. As dose perturbation is particularly troublesome in smaller photon fields, using a low-perturbation, unshielded electron field diode (EFD) in these fields is of interest. The aim of this work was to investigate the ...
