Conducting mechanism in the epitaxial p-type transparent conducting oxide Cr2O3:Mg
SHVETS, IGOR; FARRELL, LEO; FLEISCHER, KARSTEN (2015)Epitaxial p -type transparent conducting oxide (TCO) Cr 2 O 3 :Mg was grown by electron-beam evaporation in a molecular beam epitaxy system on c -plane sapphire. The influence of Mg dopants and the oxygen partial ... -
Decoupling the refractive index from the electrical properties of transparent conducting oxides via periodic superlattices
FLEISCHER, KARSTEN; CAFFREY, DAVID; NORTON, EMMA; Ó COILEÁIN, CORMAC; SMITH, CHRISTOPHER; FARRELL, LEO; SHVETS, IGOR (2016) -
Raman spectra of p-type transparent semiconducting Cr<inf>2</inf>O<inf>3</inf>:Mg
SHVETS, IGOR; FLEISCHER, KARSTEN; CAFFREY, DAVID; FARRELL, LEO; NORTON, EMMA; MULLARKEY, DARAGH; ARCA, ELISABETTA (2015)Abstract We present an analysis of the Raman spectra of p-type transparent conducting Cr2O3:Mg grown by various techniques including spray pyrolysis, pulsed laser deposition, molecular beam epitaxy and reactive magnetron ... -
Reflectance anisotropy spectroscopy of magnetite (110) surfaces
MAUIT, OZHET; SMITH, CHRISTOPHER; FLEISCHER, KARSTEN; FARRELL, LEO; MCGILP, JOHN; SHVETS, IGOR (2014)Reflectance anisotropy spectroscopy (RAS) has been used to measure the optical anisotropies of bulk and thin-film Fe3O4(110) surfaces. The spectra indicate that small shifts in energy of the optical transitions, ... -
Spray pyrolysis growth of a high figure of merit, nano-crystalline, p-type transparent conducting material at low temperature
FLEISCHER, KARSTEN; FARRELL, LEO; SHVETS, IGOR; CAFFREY, DAVID; NORTON, EMMA; O'DOWD, BRENDAN (2015) -
Synthesis of nanocrystalline Cu deficient CuCrO2 a high figure of merit p-type transparent semiconductor
FLEISCHER, KARSTEN; FARRELL, LEO; NORTON, EMMA; SHVETS, IGOR; CAFFREY, DAVID; SMITH, CHRISTOPHER (2016) -
X-ray spectroscopic studies of the electronic structure of chromium-based p-type transparent conducting oxides
FLEISCHER, KARSTEN; NORTON, EMMA; CALLAGHAN, STEPHEN; MCGUINNESS, CORMAC; FARRELL, LEO; SHVETS, IGOR (2016)The valence band structure of p-type transparent oxides—crystalline MgxCr2−xO3 and nanocrystalline CuxCrOy—is analyzed as a function of incoming photon energy. The valence band of both p-type transparent conducting oxides ...
