Optoelectronic semiconductors play a pivotal role in modern technology, enabling the conversion of electronic signals into optical signals and vice versa. These materials are at the heart of numerous devices that have become integral to our daily lives, ranging from laser diodes and light-emitting diodes (LEDs) to photodetectors and solar cells and imaging displays. Optoelectronic semiconductors utilize the unique properties of semiconducting materials to manipulate and control the flow of photons and electrons. One of the defining characteristics of optoelectronic semiconductors is their ability to absorb, emit, or modulate light. To achieve this goal, semiconductor materials are carefully engineered and often combined in heterostructures to tailor their optical and electronic properties to specific applications.
