Crystal Films Grow on 'Universal' Substrate

Facebook X LinkedIn Email
Cornell University researchers are in the preliminary stages of demonstrating that crystals of any material can be grown on a substrate. If the technique proves successful, it could open the door for manufacturing a whole new class of optoelectronics devices including lasers, detectors, sensors and imaging systems. A major obstacle to the manufacture of various semiconductors is that single-crystal semiconductor thin films must be deposited on a crystal of the same lattice structure, otherwise defects will result and the semiconductor cannot be used. Even a 1 percent mismatch in lattice...Read full article
