Abstract
The present disclosure relates to a method that includes contacting a surface of a first layer that includes a Group III element and a Group V element with a gas that includes HCl, where the first layer is positioned in thermal contact with a wafer positioned in a chamber of a reactor, and the contacting results in a roughening of the surface.
Claims20
A method comprising:
- contacting a surface of a first layer comprising a Group III element and a Group V element with a gas comprising HCl, wherein:
- the first layer is positioned in thermal contact with a wafer positioned in a chamber of a reactor, and
- the contacting results in a roughening of the surface.
A device comprising:
- a first layer having a roughened surface and comprising a Group III element and Group V element;
- a second layer comprising a reflective metal;
- and
- a third layer comprising a Group III element and Group V element, wherein:
- the second layer is in physical contact with the roughened surface,
- the third layer has a thickness between 100 nm and 500 nm, and
- the first layer is positioned between the second layer and the third layer.
