The paper describes the infrared (IR) thermal measurement facility at De Montfort University and the use of the facility to make IR temperature measurements on RF devices. Some of the limitations with conventional IR measurements will be described; including effects related to the low emissivity and optical transparency of materials. A novel method for improving the accuracy of IR temperature m...

The optical properties of GaAs nano-wires grown on shallow-trench-patterned Si(001) substrates were investigated by cathodoluminescence. The results showed that when the trench width ranges from 80 to 100 nm, the emission efficiency of GaAs can be enhanced and is stronger than that of a homogeneously grown epilayer. The suppression of non-radiative centers is attributed to the trapping of both ...
