Ge and III–V compounds, semiconductors with excessive provider mobilities, are applicants to exchange Si because the channel in MOS units. 2nd fabrics – like graphene and MoS_2 – also are expected to switch Si within the future.
This thesis is dedicated to the first-principles modeling of the vibrational houses of those novel channel materials.
The first a part of the thesis makes a speciality of the vibrational houses of varied oxides on Ge, making it attainable to spot the vibrational signature of particular defects that can impede the right kind functioning of MOSFETs.
The moment a part of the thesis stories at the digital and vibrational houses of novel second fabrics like silicene and germanene, the Si and Ge second opposite numbers of graphene. The interplay of those 2nd fabrics with steel and non-metallic substrates is investigated. It used to be anticipated, for the 1st time, and later experimentally proven, that silicene should be grown on a non-metallic template like MoS_2, a step forward that may open the door to the prospective use of silicene in destiny nanoelectronic devices.
