PdNeuRAM: forming-free, multi-bit Pd/HfO2 ReRAM for energy-efficient neuromorphic computing

Erbing Hua, Theofilos Spyrou, Majid R. Ahmadi, Hanzhi Xun et autres

Memristor technology offers a promising route toward energy-efficient computing but faces challenges including resistance drift, variability, and the need for electroforming. Filamentary resistive random-access memory, one of the most studied memristive platforms, typically requires a high-voltage electroforming step to initiate conductive filaments, …

Tracking Water Splitting Activity by Cocatalyst Identity in SrTiO3

Nursaya Zhumabay, Jeremy A. Bau, Rafia Ahmad, Laurentiu Braic et autres

Photocatalytic water splitting is the most idealistic route to green hydrogen production, but the extensive material requirements for this reaction make it difficult to realize good photocatalysts. Noble metal cocatalysts are often added to photocatalysts to aid in charge separation and improve …

Li-doped IrO2/Si heterojunctions for CMOS-integrated optoelectronics

Abdullah Alquwayzani, Laurentiu Braic, Mohamed Nejib Hedhili, Tien Khee Ng et autres

The heterojunction of polycrystalline Li-doped IrO2, grown by pulsed laser deposition, and (100)-oriented Si is investigated to develop CMOS-integrated compact optoelectronics. The grown films exhibited p-type conductivity with a bandgap value of around 3.15 eV. Energy-dispersive x-ray spectroscopy mapping confirmed the films’ …

Ultralow-power deep-ultraviolet photodetection using oxide-nitride heterojunctions integrated on silicon

Nasir A. Alfaraj, Kuang‐Hui Li, Chun Hong Kang, Laurentiu Braic et autres

A Si-integrated oxide-nitride deep-ultraviolet photodetector with remarkable photosensitivity is demonstrated. The proposed device topology is realized through the disordered nucleation of β-Ga2O3 crystals on monocrystalline TiN interlayers forming an oxide-nitride vertical heterostructure stack housed on a Si substrate. Spectral responsivity levels of …
