The paper predicts that reducing topological insulator films to a few atomic layers, together with strain, gating, and tuned illumination, can amplify the helicity-dependent photocurrent enough to reach sub-1% chiral sensitivity.

Towards Advanced Chiral Sensors: Enhanced Helicity-Dependent Photocurrent in Ultrathin Topological Insulator Films
The paper predicts that reducing topological insulator films to a few atomic layers, together with strain, gating, and tuned illumination, can amplify the helicity-dependent photocurrent enough to reach sub-1% chiral sensitivity.
