Phase change nanoelectronic devices

Dr Ou has his interest on nanoelectronic devices based on nonvolatile phase change materials from working for the semiconductor company, Macronix International Taiwan, funded project on “phase change memory” in 2007.

After Dr Ou joined Optoelectronic Research Centre, he worked with the world leading team of phase change material, Dr Behrad Gholipour, Dr Chung-Che Huang and Professor Dan Hewak on development of CVD-grown phase change nanodevices.
