Researchers demonstrated precise bidirectional control of electron spatial arrangement in quantum electronic states without applied voltage, using interface engineering between bismuth thin films and MoS₂. The study, published in Nature Communications, achieves gate-free manipulation of electron wavefunctions in two directions simultaneously.
Interface Engineering
The team engineered interfaces between semimetal bismuth (Bi) thin films and two-dimensional semiconductor MoS₂. This approach allowed control over electron spatial arrangement in two directions without any applied voltage, a first for quantum electronic states.
Bidirectional Control
The method enables gate-free manipulation of electron wavefunctions, achieving bidirectional control simultaneously. This contrasts with conventional techniques that require external voltages and typically allow only one-directional control.
