Description
Bin Zhang and co-authors grow a protective skin on perovskite crystals for X-ray detectors, in this 2025 paper. Perovskites sense X-rays well and cheaply, but wandering ions inside them erode stability. The team used a gas-phase method to lay a flat, two-dimensional perovskite cap over a three-dimensional crystal with nanometer control.
The cap's bulky organic layers slowed ion drift, which cut defects and steadied the device. Their detector reached sensitivity among the best reported for this material class, with a fast response and very low drift. The authors present the method as a precise way to build layered perovskite devices.
