Three dimensional localization of nanoscale battery reactions using soft X-ray tomography
Young-Sang Yu, Maryam Farmand, Chunjoong Kim +16
Battery function is determined by the efficiency and reversibility of the electrochemical phase transformations at solid electrodes. The microscopic tools available to study the ch…
Spatially uniform resistance switching of low current, high endurance titanium-niobium-oxide memristors
Suhas Kumar, Noraica Davila, Ziwen Wang +6
We analyzed micrometer-scale titanium-niobium-oxide prototype memristors, which exhibited low write-power (<3 μW) and energy (<200 fJ/bit/μm2), low read-power (~nW), and high endur…
Conduction Channel Formation and Dissolution Due to Oxygen Thermophoresis/Diffusion in Hafnium Oxide Memristors
Suhas Kumar, Ziwen Wang, Xiaopeng Huang +7
Transition metal oxide memristors, or resistive random-access memory (RRAM) switches, are under intense development for storage-class memory because of their favorable operating po…
Direct Observation of Localized Radial Oxygen Migration in Functioning Tantalum Oxide Memristors
Suhas Kumar, Catherine E. Graves, John Paul Strachan +6
Oxygen migration in tantalum oxide, a promising next-generation storage material, is studied using in-operando x-ray absorption spectromicroscopy and is used to microphysically des…
In-operando synchronous time-multiplexed O K-edge x-ray absorption spectromicroscopy of functioning tantalum oxide memristors
Suhas Kumar, Catherine E. Graves, John Paul Strachan +4
Memristors are receiving keen interest because of their potential varied applications and promising large-scale information storage capabilities. Tantalum oxide is a memristive mat…
