Crystallization of Ge2Sb2Te5 films by amplified femtosecond optical pulses
Article presented new experimental and theoretical evidence of data storage in Ge:Sb:Te thin films using multiple femtosecond laser pulses. Work was supported by EPSRC grant (EP/F015046/1) in collaboration with STMicroelectronics (Italy), Plasmon Data Systems Ltd (Cambridge) and RWTH-Aachen (Germany). Work revealed a new role of multiple pulse operation in bypassing material constraints for the production of next generation of phase-change memories and microprocessors, and uncovered a new indirect method of estimating the growth velocity in phase-change materials (impacts switching speed and data retention of devices). Lead to successful funding of EPSRC project (EP/J018783/1) on mixed mode switching in phase-change media.
