TL;DR: In this article, the authors present an overview of recent achievements in the field of condensedmatter physics, including the detection of coherent phonons and phonon-polaritons with femtosecond time resolution.
Journal ArticleDOI
Local impedance imaging and spectroscopy of polycrystalline ZnO using contact atomic force microscopy
TL;DR: In this paper, a nanoimpedance microscopy/spectroscopy (NIM) method was used to study the quality of a tip/surface contact and transport behavior of individual grains and grain boundaries in polycrystalline ZnO.
Journal ArticleDOI
Characterization of device parameters in high-temperature metal-oxide-semiconductor field-effect transistors in β-SiC thin films
TL;DR: Both inversion and depletion mode n−channel MOSFETs have been fabricated on β-SiC thin films grown by chemical-vapor deposition as mentioned in this paper, and stable saturation and low subthreshold currents were achieved at drain-source voltages exceeding 5 and 25 V for the inversion-mode and depletion-mode devices, respectively.
Journal ArticleDOI
Admittance Spectroscopy of Cu-Doped ZnO Crystals
TL;DR: In this paper, an experiment to determine the electronic state of Cu in a ZnO crystal is performed using the admittance spectroscopy technique at the frequency range from 100 Hz to 100 kHz and the temperature range from -160 to +80°C.
