Impact of Sapphire Substrate Reconstruction on the Structural, Electronic, and Photonic Properties of MoS2

Small, EarlyView.
High‐temperature reconstruction of c‐plane sapphire during MOCVD growth of MoS2 fundamentally alters the optical and electronic properties of MoS2 epilayer by introducing step‐edge driven interfacial charge transfer. Raman, PL, and KPFM reveal non‐uniform doping and strain in as‐grown films, whereas transferred layers show uniform optical and ...

High‐Resolution Microlens‐Assisted Tunable n‐Type Optical Doping in Monolayer MoS2

Small, EarlyView.
The laser‐assisted microlens array processing (LAMP) technique enables sub‐diffraction, localized n‐type optical doping of monolayer MoS2 by utilizing self‐assembled microspheres as microlenses. Controlled sulfur vacancy formation under low‐power laser irradiation allows precise tuning of the carrier concentration.

Flattening Energy Puddles for Enhanced Charge Transport in Wrinkled WSe2

Small, EarlyView.
Strain‐inducing wrinkles in 1L‐WSe2 create carrier‐trapping energy puddles. Trioctylphosphine selenide (TOPSe) selectively passivates Se vacancies at these wrinkle sites, while steric hindrance suppresses basal‐plane reaction. Comprehensive suite of space‐resolved spectroscopic techniques reveals reduced nonradiative recombination, longer exciton ...
