Multiscale simulations guided advances for all-optical phase-change waveguides
Hanyi Zhang, Wanting Ma, Wen Zhou +9
Photonic computing using chalcogenide phase-change materials (PCMs) is under active development for energy-efficient artificial intelligence (AI) applications. A key requirement is…
Atomistic understanding of two-dimensional monatomic phase-change material for non-volatile optical applications
Hanyi Zhang, Xueqi Xing, Jiang-Jing Wang +8
Elemental antimony (Sb) is a promising material for phase-change memory, neuromorphic computing and nanophotonic applications, because its compositional simplicity can prevent phas…
Amorphous phase-change memory alloy with no resistance drift
Xiaozhe Wang, Ruobing Wang, Suyang Sun +12
Spontaneous structural relaxation is intrinsic to glassy materials due to their metastable nature. For phase-change materials (PCMs), the resultant temporal change in electrical re…
Role of seed layer in growing atomically flat TiTe2/Sb2Te3 heterostructure thin films at the wafer scale
Chao Nie, Xueyang Shen, Junying Zhang +8
Chalcogenide phase-change materials (PCMs) are a leading candidate for advanced memory and computing applications. Epitaxial-like growth of chalcogenide thin films at the wafer sca…
