Improved Surface Chemistry Lifts HgTe Nanocrystal Photodiode Voltage
Researchers have demonstrated that an ultrathin CdS shell combined with revised Cd‑based interface chemistry pushes HgTe nanocrystal photodiodes past a long‑standing voltage ceiling. The optimized devices achieve a 420 mV open‑circuit voltage—exceeding half the material bandgap—and reduce dark current to ~10⁻⁷ A cm⁻². Detectivity reaches 1.5 × 10¹¹ Jones at room temperature, while response times stay under 200 ns. When integrated with a dielectric Bragg cavity, the diodes deliver a narrow 90 cm⁻¹ linewidth centered at the telecom‑relevant 1.55 µm wavelength.
