STEMPix: A Phase-Transition-Material-Based Pixel Sensor for Resolving Edge-Movement Direction
Md Rahatul Islam Udoy, Sumeet Kumar Gupta, Deep Jariwala +1
This paper proposes a spatio-temporal edge-movement direction pixel (STEMPix) for generating compact direction-aware edge movement information inside a CMOS-compatible image sensor…
Neural dynamical systems on ferroelectric compute-in-memory for real-time forecasting
Keshava Katti, Adithya Selvakumar, Pratik Chaudhari +1
Neural dynamical systems are expressive temporal predictors that capture continuous-time dynamics through fine-grained state updates. However, this sequential structure maps poorly…
Controlled non-volatile modulation of optical dispersion in monolayer tungsten disulfide via ferroelectric polarization patterning
Yuhong Cao, Zekun Hu, Jason Lynch +7
The manipulation of optical properties, including reflection, refraction, polarization, phase, and frequency, has long been central to advancing photonic and optoelectronic technol…
Photoinduced metastable cation disorder in metal halide double perovskites
Shunran Li, Burak Guzelturk, Conrad A. Kocoj +18
Lead-free perovskites have emerged as environmentally benign alternatives to lead-halide counterparts for optoelectronics. Among them, the double perovskite Cs2AgInCl6 family exhib…
Electrically Tunable Excitonic-Hyperbolicity in Chirality-Pure Carbon Nanotubes
Jason Lynch, Pavel Shapturenka, Mohammad Mojtaba Sadafi +8
Metamaterials exhibiting hyperbolic dispersion enable unprecedented control over light-matter interactions, from sub-diffraction imaging to enhanced spontaneous emission. However,…
Natural Hyperbolicity of Hexagonal Boron Nitride in the Deep Ultraviolet
Bongjun Choi, Jason Lynch, Wangleong Chen +6
Hyperbolic media enable unique optical phenomena including hyperlensing, negative refraction, enhanced photonic density of states (PDOS), and highly confined polaritons. While most…
