Compositional gradient engineering for enhanced ferroelectricity in ultrathin AlScN
Zekun Hu, Haiwen Zhang, Rajeev Kumar Rai +12
Ferroelectric AlScN is promising for CMOS-compatible non-volatile memory, but thickness scaling is limited by leakage, premature breakdown, and defect-mediated failure. Here we sho…
Ultraviolet Exciton-Polaritons in Silver Phenylthiolate
Bongjun Choi, Bonnie Chen, Thuc T. Mai +8
Ultraviolet (UV) exciton-polaritons (EPs) enable nonlinear optics, polaritonic lasing, and polariton-mediated photochemistry in the short-wavelength regime, yet progress has been l…
Indium selenides for next-generation low-power computing devices
Seunguk Song, Michael Altvater, Wonchan Lee +3
As silicon-based computing approaches fundamental physical limits in energy efficiency, speed, and density, the search for complementary materials to extend or replace CMOS technol…
Understanding Optical Anisotropy in Multilayer γ-InSe and ε-GaSe
Jason Lynch, Zexuan Liu, Sergiy Krylyuk +3
Low-dimensional media have exhibited optical anisotropy that is unachievable in traditional 3D media due to the asymmetry of their strong, in-plane covalent bonds and weak out-of-p…
Self-Hybridized Exciton-Polariton Photodetectors From Layered Metal-Organic Chalcogenolates
Bongjun Choi, Adam D. Alfieri, Wangleong Chen +1
Exciton-polaritons (EPs) arising from strong light-matter coupling offer new pathways for controlling optoelectronic properties. While typically requiring closed optical cavities f…
Coercive Field Reduction in Ultra-thin Al1-XScXN via Interfacial Engineering with a Scandium Electrode
Yinuo Zhang, Rajeev Kumar Rai, Giovanni Esteves +4
Aluminum scandium nitride (AlScN) ferroelectrics are promising for next-generation non-volatile memory applications due to high remnant polarization compared with Pb(ZrxTi1-x)O3 an…
