Nanostructured surfaces with designed optical functionalities, such as metasurfaces, allow
efficient harvesting of light at the nanoscale, enhancing light–matter interactions for a wide …

Metasurfaces can be used to enhance the absorption in metallic and dielectric thin films.
Taking advantage of this property, we experimentally demonstrate the use of a commercially …

Metasurfaces are artificial thin materials that achieve optical thickness through thin
geometrical structure. This feature of metasurfaces results in unprecedented benefits for …

The thermal gradient across a thermoelectric device is the key to convert heat energy into
electricity. Here, we propose a metamaterial perfect absorber (MPA) that increases the …

This study proposes using double-layer wire-grid structures to create narrow-band, perfect
plasmonic absorbers, which depend on polarization, for the short-wavelength visible and …

A compact and responsive thermoelectric photodetector is introduced for the mid‐infrared.
By resonantly coupling mid‐infrared light to a Sb2Te3‐Bi2Te3 thermoelectric junction, a …

We report the design and fabrication of Si plasmonic waveguide local heaters with ring
resonators. Quantification of the local temperature rise is reported through analysis based …

Perfect absorption is key to achieving high responsivity of a thin-film photodetector. Here, we
report the effect of a metamaterial perfect absorber (MPA) on the external quantum efficiency …

Thermoelectric (TE) energy converters have attracted great interest due to their maintenance-
free, long-life, and high-reliability properties. However, improving the output power of TE …

Photothermal heaters are important devices for optical switches and memories based on the
thermo-optic/magneto-optic effect and phase change materials. We demonstrated …
