Spin-orbit coupling in topological insulators – Complete Phd and Masters Thesis

[ad_1]

Introduction

Spin-orbit coupling (SOC) in topological insulators has garnered significant attention in recent years due to its unique properties and potential applications in the field of spintronics. Topological insulators are materials that have insulating bulk states but conductive surface states, which are protected by time-reversal symmetry. The presence of SOC in these materials leads to interesting phenomena such as the spin Hall effect, helical edge states, and topologically protected surface states.

Background of Study

The study of SOC in topological insulators began with the theoretical work of Kane and Mele in 2005, who predicted the existence of a new class of materials with non-trivial topological properties. Since then, extensive experimental and theoretical research has been conducted to explore the properties and potential applications of these materials.

Problem Statement

Despite the progress made in understanding the role of SOC in topological insulators, there are still many unanswered questions and challenges that need to be addressed. For example, the mechanisms through which SOC influences the electronic and spintronic properties of these materials are not fully understood.

Objective of Study

The main objective of this thesis is to investigate the impact of SOC on the electronic and spintronic properties of topological insulators. By studying the behavior of spin-polarized electrons in these materials, we aim to gain a better understanding of the underlying physics and potential applications of SOC in topological insulators.

Limitation of Study

This study is limited to theoretical and computational analysis of the electronic and spintronic properties of topological insulators with SOC. Experimental validation of the results obtained in this study is beyond the scope of this thesis.

Scope of Study

The scope of this study includes a comprehensive literature review on the topic of SOC in topological insulators, followed by a detailed analysis of the electronic and spintronic properties of these materials using theoretical and computational methods.

Significance of Study

This study is significant as it contributes to the current understanding of the role of SOC in topological insulators and may lead to the development of new technologies in the field of spintronics.
