Abstract

Recently, an extreme narrowband spectral response of only 8 nm in electronic-grade diamond-based photodetectors has been observed by Zheng Wei and his colleagues from Sun Yat-sen University for the first time. A charge collection narrowing mechanism assisted by free exciton radiative recombination is proposed, which well reveals the characteristic spectral response of diamond.
