WebJan 1, 1989 · Abstract. In this letter it is proposed that specific optical features in the infrared spectrum of the high- Tc superconductors are caused by InterValence Charge Transfer (IVCT) transitions. An IVCT transition involves optical transfer of an electron from one cation to another. It is proposed that when charge carriers are localized as a result ...

WebDec 26, 2024 · Efficient interlayer charge transfer in van der Waals heterostructures has been observed by femtosecond transient absorption and steady-state optical spectroscopy measurements, based on measuring the interlayer carrier distribution. WebMay 14, 2009 · The coloration mechanism of WO 3 was modeled as an intervalence charge transfer between W 5+ and W 6+ states [12]. Recently, it has been proposed that W 4+ states are included in substoichiometric tungsten oxide, and that the transitions between W 4+ and W 5+ states are contributed to optical absorption [13], [14], [15].
