ABSTRACT

The Pockels effect is an electro-optic effect originated from the second-order nonlinear optical effect. It induces refractive index changes proportional to applied electric fields. The influence of wavefunction shapes on the Pockels effect is predicted using molecular orbital calculations. The capability of the ultrathin/conformal organic material growth has led to many applications. George et al. developed a growth process for hybrid organic-inorganic polymer films by combining molecular layer deposition with atomic layer deposition, and the films were used as gate insulators for organic thin-film transistors, thin-film encapsulations for organic light-emitting diodes, and energy technologies including batteries and thermoelectric energy devices. Three source molecules, namely, terephthalaldehyde (TPA), p-phenylenediamine (PPDA), and oxalic dihydrazide (ODH), are connected with a sequence of ODH-TPA-PPDA-TPA-ODH-. When TPA and PPDA are connected by chemical reactions, p electrons pass through the bond. When TPA and ODH are connected, on the other hand, p electrons are blocked by a series of single bonds. By using such bond characteristics, various kinds of polymer multiple quantum dots can be fabricated.
