Semiconductors (transistors, lasers, solar cells)Gallium arsenide is used in semiconductor applications. It is also used in the manufacture of devices such as microwave frequency integrated circuits, Gunn diodes, monolithic microwave integrated circuits, infrared light-emitting diodes, laser diodes and optical windows. Further, it is used for single-crystalline thin film solar cells and multi-junction solar cells. In addition, it is used for the detection of X-rays.
