2008 (English)In: High Pressure Research vol. 28 issue 4 December 2008: Proceedings of the 46th European High pressure Research Group Meeting (EHPRG 46), Valencia (Spain), September 2008, London: Taylor & Francis , 2008, 597-600 p.Conference paper (Refereed)
In search of structural phase transformations, the electrical resistances of the alkali metal-intercalated fullerene compounds Li4C60, Na4C60, and Rb4C60 have been measured as functions of temperature and pressure. The compounds have different lattice structures, and in the first two, the fullerene molecules form two-dimensional covalently bonded polymer lattices. No phase changes could be identified over the ranges 100-400 K and 0-2 GPa. All materials are semiconducting under the conditions studied, and we see no strong dependence of the band gaps on pressure.
