Company AXT, Inc.

AXT, Inc. is a material science company that develops and manufactures high-performance compound and single element semiconductor wafer substrates comprising indium phosphide (InP), gallium arsenide (GaAs) and germanium (Ge). Its wafer substrates are used when a typical silicon wafer substrate cannot meet the performance requirements of a semiconductor or optoelectronic device. It has two product lines: specialty material substrates and raw materials integral to these substrates. Its InP is a semiconductor wafer substrate used in broadband and fiber optic applications, 5G infrastructure and data center connectivity. Its semi-conducting GaAs substrates are used to create opto-electronic products, including high brightness light emitting diodes that are often used to backlight wireless handsets and LCD televisions and for automotive, signage, and lighting applications. Its Ge substrates are used in applications, such as solar cells for space and terrestrial photovoltaic applications.
