amorphous silicon

Silicon that has a disordered atomic structure. Because it can be vapor deposited onto large substrates, amorphous silicon is used to create thin film transistors on almost all active matrix LCD screens as well as thin film photovoltaic cells on solar panels manufactured in long sheets. Contrast with crystalline silicon. See amorphous semiconductor and LTPS LCD.
