Bioheterojunction Effect on Fluorescence Origin and Efficiency Improvement of Firefly Chromophores
Duanjun Cai, Miguel A. L. Marques, Bruce F. Milne +1
We propose the heterojunction effect in the analysis of the fluorescence mechanism of the firefly chromophore. Following this analysis, and with respect to the HOMO-LUMO gap alignm…
Non-contact electrical detection of intrinsic local charge and internal electric field at nanointerfaces
Duanjun Cai, Fuchun Xu, Jinchai Li +2
A nanoscale non-contact electrical measurement has been developed based on Auger electron spectroscopy. This approach used the speciality of Auger electron, which is self-generated…
Tuning linear and nonlinear optical properties of wurtzite GaN by c-axial stress
Duanjun Cai, Guang-Yu Guo
We study the linear and nonlinear optical properties of wurtzite GaN under c-axial stress field, using density functional theory calculations. The fully structural optimization at…
Microscopic origin of light emission in Al_yGa_{1-y}N/GaN superlattice: Band profile and active site
Duanjun Cai, Junyong Kang, Guang-Yu Guo
We present first-principles calculations of AlGaN/GaN superlattice, clarifying the microscopic origin of the light emission and revealing the effect of local polarization within th…
