Ultrabroadband THz/IR upconversion and photovoltaic response in semi-conductor ratchet based upconverter
Peng Bai, Ning Yang1, Weidong Chu +12
An ultrabroadband upconversion device is demonstrated by direct tandem integration of a p-type GaAs/AlxGa1-xAs ratchet photodetector (RP) with a GaAs double heterojunction LED (DH-…
Realization of ultrabroadband THz/IR photoresponse in a bias-tunable ratchet photodetector
Peng Bai, Xiaohong Li, Ning Yang +14
High performance Terahertz (THz) photodetector has drawn wide attention and got great improvement due to its significant application in biomedical, astrophysics, nondestructive ins…
Statistical Kinetics of Phase-Transforming Nanoparticles in LiFePO4 Porous Electrodes
Peng Bai, Guangyu Tian
Using a simple mathematical model, we demonstrate that statistical kinetics of phase-transforming nanoparticles in porous electrodes results in macroscopic non-monotonic transient…
Suppression of Phase Separation in LiFePO4 Nanoparticles During Battery Discharge
Peng Bai, Daniel A. Cogswell, Martin Z. Bazant
Using a novel electrochemical phase-field model, we question the common belief that LixFePO4 nanoparticles separate into Li-rich and Li-poor phases during battery discharge. For sm…
