Abstract
Hall effects, in general, are transport phenomena, in which an applied field on the
particles results in a motion perpendicular to the field. In traditional Hall effect and
its quantum versions charges are transported by the action of a Lorentz force. The
spin Hall effect(SHE) and its quantum versions are a relativistic spin orbit coupling
phenomenon allow to create and manipulate the spin, and generate a spin current.
It is of particular importance to the development of transistor like devices. The
spin orbit interaction responsible for the SHE is also expected to cause the inverse
process of the SHE. The inverse spin Hall effect (ISHE) is a process that converts
a spin current into an electric current. The quantum spin Hall effect allows for the
existence of an unusual type of material called a topological insulator without external
magnetic field which conducts electricity on the surface but not through the bulk of
the material and my finding shows the plot of resistivity versus quantized magnetic
field is plateau.
