Hot electron cooling in InSb probed by ultrafast time-resolved terahertz cyclotron resonance
Chelsea Q. Xia, Maurizio Monti, Jessica L. Boland +4
Measuring terahertz (THz) conductivity on an ultrafast time scale is an excellent way to observe charge-carrier dynamics in semiconductors as a function of time after photoexcitati…
Limits to Electrical Mobility in Lead-Halide Perovskite Semiconductors
Chelsea Q. Xia, Jiali Peng, Samuel Poncé +11
Semiconducting polycrystalline thin films are cheap to produce and can be deposited on flexible substrates, yet high-performance electronic devices usually utilize single-crystal s…
Elucidating the long-range charge carrier mobility in metal halide perovskite thin films
Jongchul Lim, Maximilian T. Hoerantner, Nobuya Sakai +9
Many optoelectronic properties have been reported for lead halide perovskite polycrystalline films. However, ambiguities in the evaluation of these properties remain, especially fo…
CsInAgCl: A new lead-free halide double perovskite with direct band gap
George Volonakis, Amir A. Haghighirad, Rebecca L. Milot +7
ABBX halide double perovskites based on bismuth and silver have recently been proposed as potential environmentally-friendly alternatives to lead-based hybrid hali…
Perovskite-perovskite tandem photovoltaics with optimized bandgaps
Giles E. Eperon, Tomas Leijtens, Kevin A. Bush +24
We demonstrate four and two-terminal perovskite-perovskite tandem solar cells with ideally matched bandgaps. We develop an infrared absorbing 1.2eV bandgap perovskite, $FA_{0.75}Cs…
Extreme sensitivity of graphene photoconductivity to environmental gases
Callum J. Docherty, Cheng-Te Lin, Hannah J. Joyce +4
Graphene is a single layer of covalently bonded carbon atoms, which was discovered only 8 years ago and yet has already attracted intense research and commercial interest. Initial…
