Theory of Trapped‐Hole Centers in Rare‐Gas Solids

摘要: Experimental evidence suggests that self‐trapping of holes occurs in rare‐gas solids. Formation an intrinsic diatomic center, similar to the Vk is investigated as a possible mechanism. The energy trapping valence‐band hole discussed on basis simple model for center. A method calculating relaxation and polarization energies developed, appropriate parameters estimated, applied solid argon, krypton, xenon determine degree contributions energy. results suggest stable trapped‐hole centers at 0°K associated with only small lattice relaxations. internal molecular binding center found be overwhelming factor determining its configuration this model.
