High-entropy alloys (HEAs) including Ni and other 3d transition metals present a unique
class of materials characterized by single phase solid solutions in face-centered cubic …

Two recent electronic transport experiments from Columbia University and Harvard
University have reported record high mobility and low channel densities in flux-grown …

Hydrostatic pressure (P) has been regarded as an effective approach to improve the
performance of thermoelectric materials. Although a positive correlation between its …

We thoroughly investigated the anharmonic lattice dynamics and microscopic mechanisms
of the thermal and electronic transport characteristics in orthorhombic o-CsCu5S3 at the …

Considering theoretically the transition between hydrodynamic and ballistic regimes in 2D
semiconductors, we show that electrons in high-mobility 2D GaAs are by far the best system …

Antiperovskite materials have garnered significant attention due to their rich array of physical
properties. In this study, we undertake a theoretical exploration into the phase stabilities, and …

We developed the theory of hydrodynamics of an isotropic Fermi liquid of electrons coupled
to isotropic acoustic phonons, assuming that umklapp processes may be neglected. At low …

We have used a combination of linear response time-domain THz spectroscopy (TDTS) and
nonlinear THz pump-probe spectroscopy to separately probe the electronic momentum and …

A theoretical understanding of the enigmatic linear-in-temperature (T) resistivity, ubiquitous
in strongly correlated metallic systems, has been a long sought-after goal. Furthermore, the …

Hafnium diboride (HfB2) is an important metallic ceramic that works in harsh environments,
due to its high strength and thermal conductivity. Although the thermal conductivity of HfB2 …
