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…
Tuning Breakdown-to-Coercive Field Ratio in Ultra-Thin Al1-xScxN Films via Reactive Nitrogen Atmosphere
Yinuo Zhang, Walter J. Smith, Giovanni Esteves +3
Al1-xScxN has attracted significant interest due to its large remnant polarization and low processing temperature when compared to other ferroelectric material systems. However, de…
Hydrazine-Free Precursor for Solution-Processed All-Inorganic Se and Se1-xTex Photovoltaics
Adam D. Alfieri, Swarnendu Das, Kim Kisslinger +5
Selenium (Se) has reemerged as a promising absorber material for indoor and tandem photovoltaics (PVs), and its alloys with Te (Se1-xTex) offer a widely tunable bandgap. Solution p…
Write Cycling Endurance Exceeding 1010 in Sub-50 nm Ferroelectric AlScN
Hyunmin Cho, Yubo Wang, Chloe Leblanc +5
Wurtzite ferroelectrics, particularly aluminum scandium nitride (AlScN), have emerged as a promising materials platform for nonvolatile memories, offering high polarization values…
