Journal ArticleDOI
Long-range hot-carrier transport in hybrid perovskites visualized by ultrafast microscopy.
TL;DR: Direct visualization of hot-carrier migration in methylammonium lead iodide (CH3NH3PbI3) thin films by ultrafast transient absorption microscopy is reported, demonstrating three distinct transport regimes.
Journal ArticleDOI

TL;DR: In this paper, the thermal conductivities of β-Ga2O3 single crystals along four different crystal directions were measured in the temperature range of 80 −495 K using the time domain thermoreflectance method.
Journal ArticleDOI
Intrinsic electron mobility limits in β-Ga2O3
TL;DR: By systematically comparing experimental and theoretical transport properties, the authors identified the polar optical phonon scattering as the dominant mechanism limiting electron mobility in β-Ga2O3 to <200 cm2/V
Journal ArticleDOI
Spatial and temporal imaging of long-range charge transport in perovskite thin films by ultrafast microscopy
TL;DR: The spatially and temporally resolved measurements reported here underscore the importance of the local morphology and establish an important first step towards discerning the underlying transport properties of perovskite materials.
Journal ArticleDOI
Intrinsic Electron Mobility Limits in beta-Ga2O3
TL;DR: In this article, the authors identify the polar optical phonon scattering as the dominant mechanism limiting electron mobility in beta-Ga2O3 to lower than 200 cm2/Vs at 300 K for donor doping densities lower than 1018 cm-3.
