Tholakele F Shabangu et al.
TThe hydrogen evolution reaction (HER) from water-splitting electrolysis in a non-acidic medium produces pure hydrogen gas on a large scale. Therefore, exploring highly abundant electrocatalysts free from precious group metals (PGMs) is sig...
Dual-material-gate engineering for GIDL suppression and pillar aspect-ratio reduction in 4F2vertical DRAM cell transistors [0.03%]
用于抑制4F^2垂直DRAM单元晶体管GIDL和减小pillar纵横比的双材料栅工程技术
Donghyeon Kim,Sehoon Jung,Minju Kim et al.
Donghyeon Kim et al.
A key scaling challenge in 4F2vertical DRAM cell transistors is that gate-induced drain leakage (GIDL) suppression conventionally requires a long lightly doped drain (LDD) region, which increases the vertical pillar height and exacerbates t...
Aging-induced nanocrystalline boundary coalescence in solutionprocess synaptic memristor [0.03%]
