Infrared Nanoimaging of Hydrogenated Perovskite Nickelate Synaptic Devices
Sampath Gamage, Sukriti Manna, Marc Zajac +13
Solid-state devices made from correlated oxides such as perovskite nickelates are promising for neuromorphic computing by mimicking biological synaptic function. However, comprehen…
Electrically tunable VO2-metal metasurface for mid-infrared switching, limiting, and nonlinear isolation
Jonathan King, Chenghao Wan, Tae Joon Park +4
We demonstrate an electrically controlled metal-VO2 metasurface for the mid-wave infrared that simultaneously functions as a tunable optical switch, an optical limiter with a tunab…
Efficient Probabilistic Computing with Stochastic Perovskite Nickelates
Tae Joon Park, Kemal Selcuk, Hai-Tian Zhang +8
Probabilistic computing has emerged as a viable approach to solve hard optimization problems. Devices with inherent stochasticity can greatly simplify their implementation in elect…
Quantum materials for energy-efficient neuromorphic computing
Axel Hoffmann, Shriram Ramanathan, Julie Grollier +16
Neuromorphic computing approaches become increasingly important as we address future needs for efficiently processing massive amounts of data. The unique attributes of quantum mate…
Wavelength-by-wavelength temperature-independent thermal radiation utilizing an insulator-metal transition
Jonathan King, Alireza Shahsafi, Zhen Zhang +7
Both the magnitude and spectrum of the blackbody-radiation distribution change with temperature. Here, we designed the temperature-dependent spectral emissivity of a coating to cou…
Tuning carrier density and phase transitions in oxide semiconductors using focused ion beams
Hongyan Mei, Alexander Koch, Chenghao Wan +10
We demonstrate spatial modification of the optical properties of thin-film metal oxides, zinc oxide and vanadium dioxide as representatives, using a commercial focused ion beam (FI…
