| Abstract |
One of the most important and interesting photonic technologies emerged recently is a device that utilizes interconversion between an electrical charge and photon, as clearly demonstrated by examples such as light-emitting diodes (LED) and solar cells. Numerous phenomena crucial to the workings of such devices occur at the interface between two layers. However, difficulty in probing the “buried” interface without damaging materials makes it challenging to investigate the interface in situ. ESFG spectroscopy is a 2nd-order nonlinear optical spectroscopy that can probe only the interfacial region intrinsically by its symmetry-forbidden nature, thus enabling the selective analysis of the electronic structures of the interface while causing no sample damage. In this study, we investigated various polymer/substrate interfaces as a model of organic semiconductor devices by ESFG spectroscopy, in order to unravel correlations that exist between interfacial electronic structures and other parameters. |
