DOI: 10.1016/j.jallcom.2017.10.201
Abstract: Abstract We performed high-pressure in situ angle dispersive X-ray diffraction (ADXRD) experiments combined with CALYPSO methodology and band structure calculations on Cu2Se up to 42.1 GPa at room temperature, and four phases were identified. The initial low-pressure… read more here.
