| 英文摘要 | Hydrogen-rich materials have fascinating physical and chemical properties such as various structures and superconductivity under high-pressure. They are believed as an alternative approach to realize the hydrogen superconducting. In the previous report ([17] Zhong et al., J. Phys. Chem. C 116 (2012) 5225), we had presented structural phase-transitions and bonding interaction variations induced by pressure, and predicted a stable and superconductive phase above 220 GPa, P21/c. In this study, we focus on the change of superconducting transition temperature induced by pressure above 220 GPa for GeH4(H2)2. The variations of bond lengths, electronic structures, phonon spectra, and electron–phonon interaction with the increases of pressure are investigated. We find that the superconducting transition temperature monotonously decreases with the increase of pressure from 230 to 350 GPa. The origin is mainly the stiff of phonon frequency induced by pressurization. |
