Driving non-trivial quantum phases in conventional semiconductors with intense excitonic fields
Vivek Pareek, David R. Bacon, Xing Zhu +12
Inducing novel quantum phases and topologies in materials using intense light fields is a key objective of modern condensed matter physics, but nonetheless faces significant experi…
Dominating Interlayer Resonant Energy Transfer in Type-II 2D Heterostructure
Arka Karmakar, Abdullah Al-Mahboob, Christopher E. Petoukhoff +5
Type-II heterostructures (HSs) are essential components of modern electronic and optoelectronic devices. Earlier studies have found that in type-II transition metal dichalcogenide…
Visualizing superconductivity in an inversion-symmetry-broken doped Weyl semimetal
Zhenyu Wang, Jorge Olivares, Hiromasa Namiki +5
The Weyl semimetal MoTe offers a rare opportunity to study the interplay between Weyl physics and superconductivity. Recent studies have found that Se substitution can boost th…
Moiré-localized interlayer exciton wavefunctions captured by imaging its electron and hole constituents
Ouri Karni, Elyse Barré, Vivek Pareek +21
Interlayer excitons (ILXs) - electron-hole pairs bound across two atomically thin layered semiconductors - have emerged as attractive platforms to study exciton condensation, singl…
Unraveling the varied nature and roles of defects in hybrid halide perovskites with time-resolved photoemission electron microscopy
Sofiia Kosar, Andrew J. Winchester, Tiarnan A. S. Doherty +9
With rapidly growing photoconversion efficiencies, hybrid perovskite solar cells have emerged as promising contenders for next generation, low-cost photovoltaic technologies. Yet,…
Local Nanoscale Defective Phase Impurities Are the Sites of Degradation in Halide Perovskite Devices
Stuart Macpherson, Tiarnan A. S. Doherty, Andrew J. Winchester +12
Halide perovskites excel in the pursuit of highly efficient thin film photovoltaics, with power conversion efficiencies reaching 25.5% in single junction and 29.5% in tandem halide…
