Ultrathin Carbon Interlayer-Enabled Enhancement of Threshold-Voltage Window and Switching Reliability in Ge2Se3Te5 Selector-Only Memory Devices

Selector-only memory (SOM) has attracted attention as a promising memory technology because it enables programmable threshold-voltage state separation using a single ovonic threshold switch (OTS) device. In SOM devices, the electrode–chalcogenide interface strongly affects the threshold-voltage difference (ΔVth) and...

Fabrication of Multilayer Core-Shell Structure for High Power Factor in Bi2Te2.7Se0.3 Thermoelectrics

Bi₂Te₃-based thermoelectric materials are attractive near room temperature, but their performance is constrained by sensitive carrier-concentration control, strong crystallographic anisotropy, and compositional instability from volatile Te. Here, a multilayer core-shell structure was fabricated by conformally coating B...
