Description
Priyanka Das, Satyajit Saha, and Amit Kumar Bhunia build light sensors from cadmium and zinc sulfide nanostructures in a 2026 study. The devices rest on Schottky barriers formed against silver contacts.
Cadmium sulfide nanorods, zinc sulfide nanoparticles, and a half-and-half mix were grown by simple precipitation and coated by spin coating. All three sensors rectified current strongly, up to a million-fold within one volt in the dark. The nanorod device proved most sensitive, with detectivity near 2.75 × 10^5 jones and rise and fall times near 187 and 194 ms. Each device also showed switchable photocurrent. The zinc sulfide version trailed on most measures.
