Properties of amorphous silicon tin alloys produced using the radio frequency glow discharge technique

Abstract
Amorphous silicon tin films have been deposited by the glow discharge technique using SiH4, H2, and SnCl4 or Sn (CH3)4 gas mixtures. An n to p-type conductivity transition with increasing Sn content in the films is found for both types of Sn alloying sources. Such a transition satisfactorily explains the observed dark and light conductivity behavior.
