Effect of underlap and gate length on device performance of an AlInN/GaN underlap MOSFET

引用

Journal of Semiconductors 2012年第12期33卷 16-22页

作者： Hemant Pardeshi Sudhansu Kumar Pati godwin Raj N Mohankumar Chandan Kumar Sarkar Nano device Simulation Laboratory Electronics and Telecommunication Engineering DepartmentJadavpur University SKP Engineering College

We investigate the performance of an 18 nm gate length AIInN/GaN heterostructure underlap double gate MOSFET, using 2d Sentaurus TCAd simulation. The device uses lattice-matched wideband Al0.83In0.17N and narrowband GaN layers, along with high-k Al2O3 as the gate dielectric. The device has an ultrathin body and is designed according to the ITRS specifications. The simulation is done using the hydrodynamic model and interface traps are also considered. due to the large two-dimensional electron gas （2dEG） density and high velocity, the maximal drain current density achieved is very high. Extensive device simulation of the major device performance metrics such as drain induced barrier lowering （dIBL）, subthreshold slope （SS）, delay, threshold voltage （Vt）, Ion/Ioff ratio and energy delay product have been done for a wide range of gate and underlap lengths. Encouraging results for delay, Ion, dIBL and energy delay product are obtained. The results indicate that there is a need to optimize theIoff and SS values for specific logic design. The proposed AlInN/GaN heterostructure underlap dG MOSFET shows excellent promise as one of the candidates to substitute currently used MOSFETs for future high speed applications.

Predicting Soil Corrosivity along a Pipeline Route in the Niger delta Basin Using Geoelectrical Method: Implications for Corrosion Control

引用

Engineering（科研） 2013年第3期5卷 237-244页

作者： Kenneth S. Okiongbo godwin Ogobiri department of Geology & Physics Niger Delta University Bayelsa State Nigeria

The corrosivity of the top three metres of the soil along a pipeline route was determined using soil electrical resistivity for the emplacement of a conduit intended to serve as a gas pipeline. Fifty-six Schlumberger vertical electrical soundings (VES) were carried using a maximum current electrode separation ranging between 24 - 100 m at 2.0 km interval. The data was interpreted using a 1d inversion technique software (1X1d, Interpex, USA). Model resistivity values were classified in terms of the degree of corrosivity. Generally, the sub-soil condition along the pipeline route is non-aggressive but being slightly or moderately aggressive in certain areas due to local conditions prevailing at the measuring stations. Based on the corrosivity along the pipeline route, appropriate cathodic protection methods are prescribed.
