Phase change memory based on SnSe4 alloy 

Karanja, J. M.; Karimi, P. M.; Njoroge, W. K.; Wamwangi, D. M. (Thin Solid Films, 2013-01-01)
A phase change alloy has been synthesized and characterized. The reversible phase transitions between amorphous and crystalline states of SnSe4 films have been studied using variable electrical pulses and X-ray diffraction. ...
