    Numerical Analysis of a Si based Gate All Around Metal Semiconductor Field Effect Transistor
    (East West University, 4/4/2018) Rahman, Mahsab Al; Ratree, Maliha Marjan
    With the advent in time, as the Moore’s law approaches horizon; novel semiconductor devices such as the Gate All Around Metal Semiconductor Field Effect Transistor (GAA-MESFET) transistor arrives at the stage as the next big thing in the world of electronics. This is because as the dimensions planar MOSFET shrinks to an even smaller scale, the increase in SCE(Short Channel Effect) becomes even more prominent thus degrading the device’s performance. Thus the need of the hour is an transistor that can provide better control over SCE and GAA-MESFET can be just that ray of hope. It has become an extremely promising candidate in the sub 22 nm scale nano-devices due to its simpler fabrication process and remarkable short channel performances. In this undergraduate thesis, investigation of the behaviour of such GAA-MESFET by changing various physical parameters while trying to infer about its potential behaviour aka performance has been done. Use of High-K dielectric material alongside a stack of Low K and High k material as insulator was also done and its corresponding performance was observed.
