The Superior Performance Of GaN Epitaxial Wafers In Automotive Electronics

A wafer of semiconducting material formed through epitaxial growth, also referred to as an epi wafer, is used in photonics, microelectronics, spintronics, or photovoltaic applications. Gallium nitride (GaN), gallium arsenide (GaAs), or a mixture of the elements gallium, indium, aluminium, nitrogen, phosphorus, or arsenic make up the epitaxial layers. Among of the main benefits of GaN Substrate include high electron mobility, reduced switching losses, and fewer lattice mismatches, which are driving its usage in sectors including power electronics and optoelectronics. Moreover, GaN Epitaxial Wafers can be used as an optimal and superior substrate for high frequency, high speed, and high power devices. These wafers are created using the hydride vapor-phase epitaxy (HVPE) or metal organic chemical vapour phase deposition (MOCVD) methods. Several companies, including Aixtron, EpiGaN NV, Sciocs, and Semiconductor Wafer Inc., develop the GaN epitaxial wafers.


This research outcomes in a GaN Epitaxial Wafers with a lower defect density and huge quality crystalline development, which can be utilized to make huge-efficacy Light Emitting Diodes and other higher-voltage semiconductors. It also offers an essential platform for GaN-related survey into conductive oxides that can be employed to enhance device performance, rises efficacy and reduces the usage of power. The GaN epitaxial wafer must be a higher-quality wafer as it wants to be capable to manage the high frequency, so it must have a high dislocation density and be stably thermal. Generally, GaN epitaxial wafer equipment have been developed on costly SiC substrates.
