제목 Electrical properties of LaVO3 thin films
초록 LaVO3 thin films have been deposited on SrTiO3 and LaAlO3 substrate by pulsed laser deposition. The structure of LaVO3 thin films were measured by high-resolution x-ray diffraction. It indicated the epitaxial growth with (002) diffraction patterns on LaVO3 thin films and substrate. After the film growth, we measured electrical resistivity of LaVO3 thin films using van der Pauw geometry in the temperature range of 77 ~ 300 K. The resistivity vs temperature curve exhibited insulating behavior on LaAlO3 substrate. However, it exhibited metallic behavior on SrTiO3 substrate. To understand this phenomenon, we have investigated electronic reconstruction at the interface of the films and substrate.
