Making electro-optical sense with Zinc Oxide
ZnO has many properties that make it attractive for optoelectronic applications. It has a bandgap of 3.37 eV – the same as gallium nitride (GaN) – and an excitation binding energy of about 60 meV. It is transparent under visible wavelengths of light yet opaque under ultraviolet, making it a great UV sensor material. And it offers both piezoelectric and pyroelectric characteristics. However, what is really attractive about ZnO compared with GaN and other semiconductors, such as cadmium...
