Q: Can you describe the results in your paper, K R Catchpole 2004 Semicond. Sci. Technol. 19 1411-1415, and their importance for your field?
A: Our group recently reported world-record efficiencies for silicon light-emitting diodes and extremely high light emission from wafers of silicon. In my paper I introduce a new method for measuring the efficiency of light emission that doesn't rely on measuring the absorption, which can be difficult to determine for a weakly absorbing sample. The results provide an independent confirmation of the previously measured high light emission. The method should also be applicable to many new types of sample where the absorption is difficult to measure, such as quantum dots.
頼もしいね。
