Abstract

We demonstrate a single-step X-ray irradiation process that yields high-quality Cu(In_1−xGa_x)S₂ nanocrystals in colloidal solutions, with complete control of size and composition. Thin films produced by drop-casting exhibit high-quality photoresponse, confirming that our process is suitable for microelectronics applications.
