摘要

Methods of producing arrays of thin crystal grains of layered semiconductors, including the creation of stable atomic-layer-thick to micron-thick membranes of crystalline semiconductors by chemical vapor deposition.

主权项

1. A method of producing a semiconductor crystal grain on a substrate, comprising the steps of:
a) producing a defect or catalytic site on the substrate; and b) heating a first solid material source and a second solid material source in the presence of the substrate;wherein the first solid material source and the second solid material source are heated sufficiently to form a vapor; andwherein the vapors of the first material source and the second material source are deposited on the substrate at the defect or catalytic site to form a semiconductor crystal grain.
