Jul 1, 2024 · Now, physicists at MIT, the Army Research Lab, and elsewhere have achieved a record-setting level of electron mobility in a thin film of ternary tetradymite — a class of mineral that is naturally found in deep hydrothermal deposits of gold and quartz.
1 day ago · A high-dimensional photodetection system that combines a lens and a thin-film interface enables simultaneous measurements of light spectrum and polarization states, with the aid of a deep neural ...
1 day ago · Thin-Film Solar Panels. Made by depositing extremely thin layers of photovoltaic material (like amorphous silicon, cadmium telluride or copper indium gallium selenide) on glass, plastic or metal. Low efficiency ratings of 6-13%, requiring more space to generate the same power. Inexpensive at $1-$1.50 per watt but have a shorter 10-20 year lifespan.
6 days ago · It’s claimed the unified diode equation for thin-film PV provides insights into the mechanisms driving limiting charge collection and power-conversion efficiency in low-mobility PV devices.
Jun 29, 2024 · Thin-film solar cells are a type of solar cell made by depositing one or more thin layers (thin films or TFs) of photovoltaic material onto a substrate, such as glass, plastic or metal.
6 days ago · Here, we exploit nanocavities formed by second-order circular Bragg gratings (CBG), which support resonant anapole modes to achieve highly enhanced SHG in thin film lithium niobate (TFLN). The CBG nanocavity exhibits a record-high normalized conversion efficiency of 1.21 ×10−2cm2/GW under the pump intensity of 1.9 MW/cm2.

Jul 1, 2024 · In the case of strained HEO-Mn thin films, there are two factors which affects the Mn–O–Mn bond geometry: one is the aforementioned intrinsic non-uniformity resulting in locally varying Mn–O–Mn bonds and the other one is the induced epitaxial strain that is uniform, hence changes the Mn–O–Mn bond geometry in a coherent manner.
