Broadband Absorption in Patterned Metal/Weakly-Absorbing-Spacer/Metal with Graded Photonic Super-Crystal
Article studying high light absorption in two devices: a stack of Au-pattern/insulator/Au-film and a stack of Au-pattern/weakly-absorbing-material/Au-film where the Au-pattern was structured in graded photonic super-crystal. Multiple-band absorption, including one near 1500 nm, in a stack of Au-pattern/spacer/Au-film was observed.

A self-powered wireless motion sensor based on a high-surface area reverse electrowetting-on-dielectric energy harvester
Article presents a motion-sensing device with the capability of harvesting energy from low-frequency motion activities. Based on the high surface area reverse electrowetting-on-dielectric (REWOD) energy harvesting technique, mechanical modulation of the liquid generates an AC signal, which is modeled analytically and implemented in Matlab and COMSOL.

Spectroscopic, structural, and strain-dependent analysis of suspended bulk WSe2 sheets
Article utilizing Raman spectroscopy and photoluminescence (PL) spectroscopy to analyze the phononic and electronic parameters in suspended bulk WSe₂ sheets, fabricated utilizing photolithography and wet chemical etching. The findings of this work will be beneficial in analyzing thermal, optical, and mechanical properties of WSe₂ in a suspended platform for its application in electronic, thermoelectric, and mechanical sensors in the future.
