The role of nitrogen in transition-metal nitrides in electrochemical water splitting

Autor: Jamil, R, Ali, R, Loomba, S, Xian, J, Yousaf, M, Khan, K, Shabbir, B, McConville, CF, Mahmood, A, Mahmood, N

H2 as a storable fuel can be sustainably generated from direct cleavage of water with a catalytic approach. However, H2 generation is severely affected by poor catalytic activities and the instability of catalyst materials. Recently, transition-metal

The longstanding problem of interpretation of satellite structures in core level photoemission spectra of metallic systems with a low density of conduction electrons is addressed using the specific example of Sb-doped SnO$_2$. Comparison of {\it ab i

Shallow donor state of hydrogen in In2O3 and SnO2: Implications for conductivity in transparent conducting oxides

Autor: King, PDC, Lichti, RL, Celebi, YG, Gil, JM, Vilao, RC, Alberto, HV, Duarte, JP, Payne, DJ, Egdell, RG, McKenzie, I, McConville, CF, Cox, SFJ, Veal, TD

Muonium, and by analogy hydrogen, is shown to form a shallow-donor state in In2 O3 and SnO2. The paramagnetic charge state is stable below ∼50 K in In2 O3 and ∼30 K in SnO2 which, coupled with its extremely small effective hyperfine splitting in

Valence-band orbital character of CdO: A synchrotron-radiation photoelectron spectroscopy and density functional theory study

Autor: Mudd, JJ, Lee, T-L, Munoz-Sanjose, V, Zuniga-Perez, J, Payne, DJ, Egdell, RG, McConville, CF

N-type CdO is a transparent conducting oxide (TCO) which has promise in a number of areas including solar cell applications. In order to realize this potential a detailed knowledge of the electronic structure of the material is essential. In particul

Structural, optical and vibrational properties of self-assembled Pbn+1(Ti1-xFex)(n)O3n+1-delta Ruddlesden-Popper superstructures

Autor: DOIG, KI, PETERS, JJP, NAWAZ, S, WALKER, D, WALKER, M, LEES, MR, BEANLAND, R, SANCHEZ, AM, MCCONVILLE, CF, PALKAR, VR, LLOYD-HUGHES, J

Publikováno v: IndraStra Global.

Bulk crystals and thin films of PbTi1-xFexO3-delta ( PTFO) are multiferroic, exhibiting ferroelectricity and ferromagnetism at room temperature. Here we report that the Ruddlesden-Popper phase Pbn+1(Ti1-xFex)(n)O3n+1-delta forms spontaneously during

Band gap, electronic structure, and surface electron accumulation of cubic and rhombohedral In2O3

Autor: King, PDC, Veal, TD, Fuchs, F, Wang, CY, Payne, DJ, Bourlange, A, Zhang, H, Bell, GR, Cimalla, V, Ambacher, O, Egdell, RG, Bechstedt, F, McConville, CF

The bulk and surface electronic structure of In2 O3 has proved controversial, prompting the current combined experimental and theoretical investigation. The band gap of single-crystalline In2 O3 is determined as 2.93±0.15 and 3.02±0.15 eV for the c

Scanning tunnelling spectroscopy of quantized electron accumulation at in xGa 1-xN surfaces

Autor: Veal, TD, Piper, LFJ, Phillips, MR, Zareie, MH, Lu, H, Schaff, WJ, McConville, CF

Electron tunnelling spectroscopy has been used to investigate quantized levels in electron accumulation layers at InGaN surfaces. The tunnelling spectra exhibit a plateau in the normalized conductance which widens with increasing Ga-content, correspo
