Virtual Fabrication and Analog Performance of Sub-40nm Bulk MOSFET
Abstract: Virtual Fabrication of sub-40nm Bulk MOSFET is carried out under channel engineering and source drain engineering process. These structures enable more aggressive device scaling in nano-scale region because of their ability to control short channel effects. How ever during scaling the junction depth should also be scaled down, which increases parasitic resistance so silicidation technique has been applied to reduce their effects on device. Analog performance has been measured in …

Identification of Groundwater Arsenic Contaminated Vulnerability Zones in Alluvial Tract of West Bengal, India
Abstract: Underground water is regarded to be free from all types of pollutants hence it is considered to be safefor drinking. Consequentially, it is a predominant source of drinking water in several parts of the worldparticularly in the developing countries. Regrettably, empirical studies have also been conducted inother parts of the World and it is found that in twenty countries the subsurface water is contaminatedwith arsenic. Serious arsenic contamination is reported …

Probability of Liquefaction induced Ground Failure under the Earthquake Scenario in Kathmandu Valley
Abstract: Kathmandu valley is highly susceptible to liquefaction hazard due to the presence of liquefiable soil up to considerable depth, the presence of shallow ground water table and occurrence of earthquakes at regular intervals. Past studies have also shown the occurrence of liquefaction with examples of observed ejection of sand boil and formation of cracks throughout the valley during 1934 Nepal-Bihar earthquake. Events similar to these were also observed during recent …
