Identification of degradation mechanisms in field-tested CdTe modules (2006)
Journal Article
Carlsson, T., & Brinkman, A. (2006). Identification of degradation mechanisms in field-tested CdTe modules. Progress in Photovoltaics, 14(3), 213-224. https://doi.org/10.1002/pip.663

Field tests and accelerated ageing tests were conducted on CdTe photovoltaic modules with Sb-based back contacts. Significant performance degradation was observed during one and a half years of outdoor exposure. Small-area samples were prepared from...

Small polaron hopping in spinel manganates (2005)
Journal Article
Schmidt, R., Basu, A., & Brinkman, A. (2005). Small polaron hopping in spinel manganates. Physical review B, 72(11), https://doi.org/10.1103/physrevb.72.115101

The temperature dependence of small polaron hopping conduction in ceramic spinel NiMn2O4+ thermistor material has been investigated. We used a theoretical framework based on a random resistor network model to describe small polaron nearest-neighbor h... Read More about Small polaron hopping in spinel manganates.

Electron-hopping modes in NiMn₂O<SUB>4+δ</SUB> materials (2005)
Journal Article
Schmidt, R., Basu, A., Brinkman, A., Klusek, Z., & Datta, P. (2005). Electron-hopping modes in NiMn₂O4+δ materials. Applied Physics Letters, 86(7), https://doi.org/10.1063/1.1866643

The resistance versus temperature (R-T) characteristics of NiMn2O4+delta thermistors have been analyzed. In the literature, electron transport in manganate spinels is commonly described by a small-polaron model for nearest neighbor hopping, but varia...

In situ study of the effect of temperature on the electronic structure of NixMn3–xO4 + thin films using scanning tunneling spectroscopy (2002)
Journal Article
Basu, A., Brinkman, A., Klusek, Z., Datta, P., & Kowalczyk, P. (2002). In situ study of the effect of temperature on the electronic structure of NixMn3–xO4 + thin films using scanning tunneling spectroscopy. Journal of Applied Physics, 92(7), 4123-4125. https://doi.org/10.1063/1.1505690

NixMn3–xO4 + (0.4x1) are a series of cubic-spinel-structured material exhibiting a negative temperature coefficient of resistance. The resistance as a function of temperature (T) has been measured from 20 to 200 °C and the data have been fitted to a...

The growth of CdTe bulk crystals using the multi-tube physical vapour transport system (2002)
Journal Article
Sanghera, H., Cantwell, B., Aitken, N., & Brinkman, A. (2002). The growth of CdTe bulk crystals using the multi-tube physical vapour transport system. Journal of Crystal Growth, 237-239(3), 1711-1715. https://doi.org/10.1016/s0022-0248%2801%2902340-5

The control of vapour transport is central to the growth of any crystal from the gas phase and, therefore, a novel multi-tube physical vapour transport (MTPVT) system has been developed at the University of Durham which addresses this requirement dir...
