Compact Thermal Model for Vertical Nanowire Phase-Change Memory Cells

A Compact Thermal Model for Segmented Nanowire Phase-change Memory Cells

Indium selenide nanowire phase-change memory

Self-aligned nanotube-nanowire phase change memory.

A central issue of nanoelectronics concerns their fundamental scaling limits, that is, the smallest and most energy-efficient devices that can function reliably. Unlike charge-based electronics that are prone to leakage at nanoscale dimensions, memory devices based on phase change materials (PCMs) are more scalable, storing digital information as the crystalline or amorphous state of a material...

Thermal Transport in Phase Change Memory Materials

Phase change memory uses brief pulses of electrical current to induce phase transitions in chalcogenide material regions with dimensions near or even far below 50 nm. The strongly differing electrical conductivities of the crystalline and amorphous phases allow data storage at densities in excess of terabits per square inch. Nanoscale conduction heat transfer governs the figures of merit in the...
