Hydrogen-induced tunable remanent polarization in a perovskite nickelate
Yifan Yuan, Michele Kotiuga, Tae Joon Park +18
Materials with field-tunable polarization are of broad interest to condensed matter sciences and solid-state device technologies. Here, using hydrogen (H) donor doping, we modify t…
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…
Proton distribution visualization in perovskite nickelate devices utilizing nanofocused X-rays
Ivan A. Zaluzhnyy, Peter O. Sprau, Richard Tran +17
We use a 30-nm x-ray beam to study the spatially resolved properties of a SmNiO-based nanodevice that is doped with protons. The x-ray absorption spectra supported by density-f…
First Demonstration of Robust Tri-Gate \b{eta}-Ga2O3 Nano-membrane Field-Effect Transistors Operated Up to 400 °C
Hagyoul Bae, Tae Joon Park, Jinhyun Noh +4
Nano-membrane tri-gate beta-gallium oxide (\b{eta}-Ga2O3) field-effect transistors (FETs) on SiO2/Si substrate fabricated via exfoliation have been demonstrated for the first time.…
