Thermal stimulated current response in cupric oxide single crystal thin films over a wide temperature range
Thermal stimulated current response in cupric oxide single crystal thin films over a wide temperature range
Cupric oxide single crystal thin films were grown by plasma-assisted molecular beam epitaxy. X-ray diffraction, Raman spectrum and in situ reflection high-energy electron diffraction show that the thin films are 2x2 reconstructed with an in-plane compression and out-of-plane stretching. Thermal stimulated current measurement indicates that the electric polarization response presents …
