Layered cobalt oxide epitaxial films exhibiting thermoelectric <i>ZT</i> = 0.11 at room temperature

Multiferroic iron oxide thin films at room temperature.

Multiferroic behaviour at room temperature is demonstrated in ε-Fe2 O3 . The simple composition of this new ferromagnetic ferroelectric oxide and the discovery of a robust path for its thin film growth by using suitable seed layers may boost the exploitation of ε-Fe2 O3 in novel devices.

Transition Metal-Doped Oxide Semiconductor Exhibiting Room-Temperature Ferromagnetism

Colossal Terahertz Magnetoresistance at Room Temperature in Epitaxial La0.7Sr0.3MnO3 Nanocomposites and Single-Phase Thin Films.

Colossal magnetoresistance (CMR) is demonstrated at terahertz (THz) frequencies by using terahertz time-domain magnetospectroscopy to examine vertically aligned nanocomposites (VANs) and planar thin films of La0.7Sr0.3MnO3. At the Curie temperature (room temperature), the THz conductivity of the VAN was dramatically enhanced by over 2 orders of magnitude under the application of a magnetic fiel...

Robust room temperature persistent photoconductivity in polycrystalline indium oxide films

We have investigated the effects of UV irradiation on the electrical and optical properties of polycrystalline In2O3 films. We found that UV illumination at a peak wavelength of 365 nm leads to a sharp drop in resistance and increase in carrier concentration. This highly conductive state persists for a timescale of hours in air at room temperature after illumination. We observe distinct changes...
