  • Phase transitions in the Cu2S nanowires have been studied as a function of temperature and pressure. Differential scanning calorimetry (DSC) shows an endothermic process at 101.8 °C upon heating, corresponding to the phase transition from γ-Cu2S (monoclinic) to β-Cu2S (hexagonal) in the bulk (103.5 °C). However, the reverse phase transition was found to be much lower (74.8 °C). X-ray diffraction (XRD) demonstrates that the c-axis of γ-Cu2S is transformed to the c-axis of β-Cu2S owing to the positional disorder of the Cu atoms. Two high-pressure phases of Cu2S have been identified using a diamond anvil cell and the energy-dispersive XRD technique. © 2002 Elsevier Science B.V. All rights reserved.
