Chalcogenide thin films that undergo reversible phase changes show promise for next-generation nanophotonics, metasurfaces, and other emerging technologies. This general class of thin films can be switched rapidly between amorphous and crystalline phases which exhibit contrasted optical and electronic states. Despite the successful development of benchmark Ge2 Sb2 Te5 for some applications, there is a desire to identify new materials with improved performance. The Sandia LDRD team focused on the behavior of sputter-deposited (Ge2 Sb2Te5)xC1-x [0 < 1-x < 0.12] films and investigated the phase stability and key unknowns of several promising quaternary compositions.
This study confirmed increased crystallization temperatures of C-doped Ge2 Sb2 Te5 consistent with enhanced amorphous phase stability. Additional experiments involving high energy, and heavy ion irradiation explored the stability of films subjected to collision-induced disordering. Detailed characterization showed that crystalline films can be amorphized by ion irradiation (metamictization) and quaternary addition affects radiation tolerance. This study provides new insight into chalcogenide phase stability offering design pathways for future applications. The project involved collaborations with students and faculty from Sandia Alliance partner Purdue University and National/Regional partner University of Florida. This work generated multiple publications including one extensive article in the Journal of Applied Physics. PI David Adams was also recently elected Fellow and President of American Vacuum Society: Science and Technology of Materials, Interfaces and Processing.
