Summary: Silver nanostructures are important for developing efficient plasmonic materials due to their ability to produce localized surface plasmons and enhance electromagnetic fields. In this study, an optical technique was used to map the plasmons in silver nanohole array and nano-sawtooth structures. The results showed high enhancement factors up to 200 for the nano-sawtooth structure. The fabrication process for the silver nanostructures was straightforward and cost-effective.

Summary: Titanium dioxide (TiO2) nanopillar arrays (NPA) were fabricated through a low-cost nanosphere lithography (NSL) method. Self-assembled polystyrene (PS) nanosphere monolayer masks were used for etching TiO2 NPAs by inductively coupled plasma (ICP). The process conditions, including the nanosphere solution concentration, etching gas, power, and time, were studied. Large-area and highly ordered TiO2 NPAs with tunable geometries were obtained. The infrared optical properties of the TiO2 NPAs were analyzed based on the measured and calculated spectral reflections. The fabricated TiO2 NPA achieved an ultralow average reflection of -2% across a wide infrared wavelength range of 800-2000 nm, demonstrating great potential for infrared optoelectronic applications.

Summary: We demonstrated a low-cost, highly sensitive hybrid Ag-Cu substrate with enhanced absorption for the excitation laser beam via the nanosphere lithography technique. The substrate consists of a Cu nanoarray covered with Ag nanoparticles, resulting in optimized absorption for the laser beam. Raman enhancement is achieved by incorporating plasmonic hotspots formed by dense Ag nanoparticles. The hybrid Ag-Cu SERS substrates exhibit a highly sensitive and reproducible SERS activity, with potential applications in biosensors, environmental monitoring, and food safety.

Summary: This work presents the development and application of micropatterned molecular imprinting in a conductive polymer film for the detection of diclofenac molecules. The technique involves combining nanosphere lithography and electrochemical polymerization to generate a nanos-tructured polymer on a glassy carbon electrode. The resulting molecularly imprinted polymer electrode shows good recognition properties for diclofenac molecules in phosphate-buffered saline solution, with increased sensitivity and a lower limit of detection compared to a non-molecular imprinted polymer electrode.

Summary: This study proposes and simulates the design of a non-regrowth staircase channel GaN vertical trench transistor, showing excellent threshold and breakdown characteristics for high power and high frequency applications. The unique staircase design provides a variable capacitance through the gate-dielectric-semiconductor interface, resulting in a high breakdown voltage of 1.52 kV and a channel on-resistance of 2.61 m omega center dot cm(2). The variable length and doping profile in the channel region of this model offer greater flexibility to meet a wide range of device application requirements.
