Question

Why in mos2 band structure thier is splitting in valence band maximum?

Answer 1

Introduction

Valence electrons are electrons located farthest from the nucleus, in the atom's outermost energy shell, also known as the valence shell.

Valence electrons determine the reactivity of an atom because they are used in chemical bonding.

Valence Electrons and Groups

For a given atom, the number of valence electrons can also be found by using the Periodic Table of Elements.

In general, the group, or column, in which the element is listed tells you how many valence electrons it has.

Valence Electrons and Periods

For a given atom, the valence shellcan be found by looking at the Periodic Table of Elements.

The period, or row, in which the element is listed gives you the energy level on which the valence electrons are located.

Valence Electrons: Examples

How many valence electrons doeschlorine have? In which energy shell are the valence electrons located?

Answer 2

Explanation:

For triple-layer MoS2, the LC with inter-layer SOC due to the absence of inter-layer inverse symmetry in three-layer system makes the splitting complicated. The intra-layer SOC results in two main bands splitting, while in each main band, the triple-degeneracy is broken mainly due to the inter-layer SOC.
