摘要：

The insulator-to-metal transition in SnI4 and GeI4 was studied as a function of pressure up to 25 GPA by measuring the temperature dependence of the sample resistance inside a diamond-anvil cell. Both materials were found to metallize at well-defined pressures. A model proposed by Pasternak and Taylor in which the tetrahedral iodide molecules are linked to form conducting chains was found to explain both the metallization and amorphization of these molecular crystals.
