Hall Effect System

The Faculty of Engineering and Environment at Northumbria University is undergoing expansion and enhancement of its engineering materials facilities. Following recent grant successes, this includes investment in both space and equipment. In particular, we are looking to improve our materials characterisation facilities. We are looking to acquire a Hall effect system to measure resistivity/conductivity, carrier mobility and carrier concentration and type in semiconductor thin films. The system must be well suited to measure transparent conductive oxides as well as solar absorbers such as Sb2(S,Se)3, Cu2ZnSn(S,Se4) and related materials typically deposited on glass substrates. The system should be compact and benchtop and capable of reliably measuring thin film samples with low mobility (10-1 cm2/V.s or below) without compromising the measurement quality or samples with high mobility. The system should include full software and a PC to measure and extract the desired film properties with a user-friendly interface. UK training and support is paramount.
