New structural model for GeO2/Ge interface: A first-principles study

, 2011
First-principles modeling of a GeO2/Ge(001) interface reveals that sixfold GeO2, which is derived from cristobalite and is different from rutile, dramatically reduces the lattice mismatch at the interface and is much more stable than the conventional ...

Defect Driven Electronic Structure Reconfiguration and Hierarchical Phonon Suppression in Ag2Se Thermoelectrics

Advanced Science, EarlyView.
Indium substitution in Ag2Se nanocrystals simultaneously tailors electronic structure and lattice dynamics. Fermi‐level upshift and band‐gap narrowing enhance electrical transport, while defect‐induced lattice softening intensifies phonon scattering and suppresses lattice thermal conductivity.

Hybrid Heterostructures of Nanostructured Si Membrane and MoS2 for Self‐Powered Photodetectors

Advanced Electronic Materials, EarlyView.
A scalable MoS2/Si nanomesh vertical heterostructure is developed for self‐powered photodetection. The nanostructured junction enhances conductivity, expands the active heterointerface, and enables a transition from photovoltaic to avalanche‐assisted operation, delivering markedly improved photoresponse over planar counterparts.
