Interlayer coupling and gate-tunable excitons in transition metal dichalcogenide heterostructures
Shiyuan Gao, Li Yang, Catalin D. Spataru
Bilayer van der Waals (vdW) heterostructures such as MoS2/WS2 and MoSe2/WSe2 have attracted much attention recently, particularly because of their type II band alignments and the f…
Optical nonlinearities of excitons in monolayer MoS2
Daniel B. S. Soh, Christopher Rogers, Dodd J. Gray +2
We calculate linear and nonlinear optical susceptibilities arising from the excitonic states of mono- layer MoS2 for in-plane light polarizations, using second-quantized bound and…
The influence of defects on the thermal conductivity of compressed LiF
Reese E. Jones, Donald K. Ward
Defect formation in LiF, which is used as an observation window in ramp and shock experi- ments, has significant effects on its transmission properties. Given the extreme condition…
Strong Photothermoelectric Response and Contact Reactivity of the Dirac Semimetal ZrTe5
François Léonard, Wenlong Yu, Kimberlee C. Collins +4
The family of three-dimensional topological insulators opens new avenues to discover novel photophysics and to develop novel types of photodetectors. ZrTe5 has been shown to be a D…
Density-controlled quantum Hall ferromagnetic transition in a two-dimensional hole system
T. M. Lu, L. A. Tracy, D. Laroche +5
Quantum Hall ferromagnetic transitions are typically achieved by increasing the Zeeman energy through in-situ sample rotation, while transitions in systems with pseudo-spin indices…
