Photo-Induced Ultrafast Symmetry Switch in SnSe
Yadong Han, Junhong Yu, Hang Zhang +8
Layered tin selenide (SnSe) has recently emerged as a high-performance thermoelectric material with the current record for the figure of merit (ZT) observed in the high-temperature…
Temperature effect on the coupling between coherent longitudinal phonons and plasmons in n- and p-type GaAs
Jianbo Hu, Hang Zhang, Yi Sun +2
The coupling between longitudinal optical (LO) phonons and plasmons plays a fundamental role in determining the performance of doped semiconductor devices. In this work, we report…
Temperature Dependent Mean Free Path Spectra of Thermal Phonons Along the c-axis of Graphite
Hang Zhang, Xiangwen Chen, Young-Dahl Jho +1
Heat conduction in graphite has been studied for decades because of its exceptionally large thermal anisotropy. While the bulk thermal conductivities along the in-plane and cross-p…
Length Dependent Thermal Conductivity Measurements Yield Phonon Mean Free Path Spectra in Nanostructures
Hang Zhang, Chengyun Hua, Ding Ding +1
Thermal conductivity measurements over variable lengths on nanostructures such as nanowires provide important information about the mean free paths (MFPs) of the phonons responsibl…
The Best Nanoparticle Size Distribution for Minimum Thermal Conductivity
Hang Zhang, Austin J. Minnich
Which sizes of nanoparticles embedded in a crystalline solid yield the lowest thermal conductivity? Nanoparticles have long been demonstrated to reduce the thermal conductivity of…
