Emergence of Layer Stacking Disorder in c-axis Confined MoTe
James L Hart, Lopa Bhatt, Yanbing Zhu +13
The layer stacking order in 2D materials strongly affects functional properties and holds promise for next generation electronic devices. In bulk, octahedral MoTe possesses two…
Time-resolved vibrational-pump visible-probe spectroscopy for thermal conductivity measurement of metal-halide perovskites
Shunran Li, Zhenghong Dai, Linda Li +2
Understanding thermal transport at the micro- to nanoscale is crucially important for a wide range of technologies ranging from device thermal management and protection systems to…
Photothermally induced, reversible phase transition in methylammonium lead triiodide
Shunran Li, Zhenghong Dai, Conrad A. Kocoj +3
Metal halide perovskites (MHPs) are known to undergo several structural phase transitions, from lower to higher symmetry, upon heating. While structural phase transitions have been…
A Gapped Phase in Semimetallic T-WTe Induced by Lithium Intercalation
Mengjing Wang, Aakash Kumar, Hao Dong +6
The Weyl semimetal WTe has shown several correlated electronic behaviors, such as the quantum spin Hall effect, superconductivity, ferroelectricity, and a possible exciton in…
Vibrational relaxation dynamics in layered perovskite quantum wells
Li Na Quan, Yoonjae Park, Peijun Guo +8
Organic-inorganic layered perovskites are two-dimensional quantum wells with layers of lead-halide octahedra stacked between organic ligand barriers. The combination of their diele…
Phonon-pump electronic-probe study of methylammonium lead iodide reveals electronically decoupled organic and inorganic sublattices
Peijun Guo, Arun Mannodi-Kanakkithodi, Jue Gong +10
Organic-inorganic hybrid perovskites such as methylammonium lead iodide (CH3NH3PbI3) are game-changing semiconductors for solar cells and light-emitting devices owing to their exce…
Highly tunable ultra-narrow-resonances with optical nano-antenna phased arrays in the infrared
Shi-Qiang Li, Wei Zhou, Peijun Guo +6
We report our recent development in pursuing high Quality-Factor (high-Q factor) plasmonic resonances, with vertically aligned two dimensional (2-D) periodic nanorod arrays. The 2-…
