GeTe Phase Change Research at the US Army Research Laboratory

Current status of the GeTe phase change research at ARL is presented. The work covers determination of the power handling limits, both in ON and OFF condition, for state-of-the-art PCS technology. Maximum ON-state power handling, after 50 conditioning cycles, of 33dBm is reported. Experimental evidence of 75% reduction in the minimum energy to crystallize is presented. The effects of the applied external electric field are discussed. Also, initial results are shown for theoretical model of GeTe crystalization.
