This is the first post in a series highlighting interesting individual datapoints in the Citrination (citrination.com) platform. These may be obvious to those who research them directly, but a big part of our mission at Citrine is to expose interesting phenomena across different areas of materials and chemicals.
Today, I'll start with semiconductors, and particularly dielectric constants: the clamped dielectric tensor of ZnO. ZnO is incredibly cheap to make via a number of deposition techniques and can make for a nice wide-bandgap material. What I wanted to highlight today is its dielectric tensor. ZnO has a wurtzite crystal structure, so it has 2 components to its dielectric tensor.
