© 2022 Elsevier B.V.This study investigates the effects of hydrogen plasma treatment on the leakage current and capacitance characteristics of metal–insulator–semiconductor (MIS) structures on SiC substrate. The H2 plasma treatment resulted in improved breakdown voltage and reduced defect density (Nd) in an atomic-layer-deposited 30 nm-thick Al2O3 ...

Short-wave infrared (SWIR) image sensors based on colloidal quantum dots (QDs) are characterized by low cost, small pixel pitch, and spectral tunability. Adoption of QD-SWIR imagers is, however, hampered by a reliance on restricted elements such as Pb and Hg. Here, QD photodiodes, the central element of a QD image sensor, made from non-restricted I...

Close monitoring of vital physiological parameters is often key in following the evolution of certain medical conditions (e.g., diabetes, infections, post-operative status or post-traumatic injury). The allocation of trained medical staff and specialized equipment is, therefore, necessary and often translates into a clinical and economic burden on ...
Lead sulfide (PbS), a typical functional semiconductor material, has attracted serious attention due to its great potential in optoelectronics applications. However, controllable growth of PbS single-crystal film still remains a great challenge. Here, we report heteroepitaxial growth of large-scale highly crystalline PbS films on alkali salt (NaCl ...

We report the formation of “ripple” patterns by the sequential superposition of nonorthogonal surface waves excited by the spontaneous buckling of polymeric bilayers. Albeit of a different nature and micron scale compared to the familiar sedimentary ripples caused by gentle wave oscillations, we find commonalities in their topography, defects, and ...
