In Situ Electric Tuning―An Emerging STM Tactic for Probing Exotic Quantum Materials

Abstract

ISET with STM has established itself as a highly effective methodology for controlling quantum materials. This Review connects global electrostatic gating, tip-induced local gating, tip-induced voltage pulse manipulation, and in-plane electric tuning, revealing how carrier density, band structure, correlated states, and nanoscale phase transitions can be interrogated and engineered with atomic-scale precision.
