Cathodoluminescence Quantum Efficiency of Quantum Dot Thin Films



Heayoung Yoon, Christopher C. Bohn, Youngmin Lee, Seung H. Ko, Jonathan S. Steckel, Seth Coe-Sullivan, Nikolai B. Zhitenev


A thin film of quantum dots (QD) was used to visualize the local photo-response of polycrystalline CdTe solar cells by down-converting an electron beam of high energy to photons of visible light. The efficient photon generation in the QD film is compared to cathodoluminescence of high-purity bulk semiconductors and phosphor.
