Self-assembly of amino acids on noble metal surfaces : morphological, chemical and electronic control of matter at the nanoscale
… the <110> substrate axis, forming regular nanogratings with tunable periodicity. Within the nanowires, a zwitterionic dimerization scheme is revealed. STS shows that the biomolecular nanostructures act as tunable one-dimensional quantum resonators for the surface state electrons. …

Fabrication and Dynamic Tuning of Periodic Structures From Holographic Lithography
… and mechanical stability of epoxy-POSS, 1D nanogratings (AR up to 10) with controllable periodicity, filling fraction and surface roughness, were achieved, which could be directly converted to silica-like through calcination. By exploiting swelling-induced buckling of 1D SU-8 nanowalls with …

Flexible Fabrication of Multi-scale Integrated 3D Periodic Nanostructures with Phase Mask
… The second phase mask consisted of two-layered nanogratings with small sub-wavelength grating periods and phase offset control. That was designed with isotropic properties attractive for generating a complete photonic band gap (PBG). An isolation layer was used between adjacent polymer layers to …

Optical Enhancement in Periodic Plasmonic Gratings for SERS and Metal-Semiconductor-Metal Photodetectors (MSM-PDs) Applications
<p>This dissertation is aimed to numerically study the effect of plasmonic grating electrodes on the efficiency of metal-semiconductor-metal photodetectors (MSM PDs) and the sensitivity of Surface Enhanced Raman Spectroscopy (SERS). This research can benefit many areas of nanoscience and optics, …
