Abstract
Compound semiconductors play a pivotal role in modern electronic and optoelectronic device
applications due to their unique electrical properties and wide bandgap characteristics. This paper
provides a comprehensive review of the electrical characterization techniques employed in studying
compound semiconductor materials for various device applications. The review encompasses a wide
range of compound semiconductors, including III-V, II-VI, and IV-IV compounds, highlighting their
significance in devices such as light-emitting diodes (LEDs), photodetectors, solar cells, and highfrequency transistors. The paper discusses the fundamental electrical properties of compound
semiconductors, including carrier transport mechanisms, mobility, carrier concentration, and doping
profiles.
