We investigated the defect states of organic lead halide (CH3NH3PbX3: CH3NH3+) methylammonium (MA; X = Br− and I−) by using optical pulse-induced conductance transient spectroscopy. Organic lead halide single crystals having a bandgap ranging fro

Despite its use as a constituent layer for realization of a polar metal and interfacial conductivity, the microscopic study of electronic structure of CaTiO3 is still very limited. Here, we epitaxially stabilized CaTiO3 films on NdGaO3 (110) substrat

A polymer gate dielectric of poly(2-hydroxyethyl methacrylate) is introduced to the polymer thin-film transistor (TFT) with poly(3-hexylthiophene) as its active layer. With this polymer dielectric, the field-effect mobility is 0.1cm2V−1s−1. The s

A concept is introduced in which two polymer dielectrics are made cooperative in acting as the gate insulator for organic thin-film transistors. The bilayer insulator consists of a thin polymer dielectric in contact with the active layer that can ind
