Research Experience:Nanostructure fabrication by charged-particle-beam lithography (electron, helium ion, neon ion), and nanostructure characterization by electron microscopy (SEM, TEM, STEM) and spectroscopy (EFTEM, EELS) at the sub-10 nm scale.Investigation of the resolution limits of charged-particle-beam lithography at the sub-10 nm scale by analyzing: (1) the point-spread function (including the effects of spot size, electron scattering, electron energy, substrate, secondary electrons, volume plasmons, and resists); (2) the resist development; (3) the resist collapse; and (4) the line edge roughness.Numerical and Monte Carlo simulation of electron scattering and energy deposition in resists.Lithographic placement and fluorescence microscopy of single colloidal quantum dots (diameter < 10 nm).Fabrication of graphene nanoribbons by top-down (electron-beam lithography, helium ion milling, optical lithography) and bottom-up (nanoparticle catalytic etching) nanofabrication techniques.Raman spectroscopy, atomic force microscopy, and electrical characterization of graphene field effect transistors.Fabrication of sub-100 nm plasmonic antennas and characterization of surface and volume plasmons by electron energy loss spectroscopy (EELS).Investigation of electron- and ion-beam interactions with matter for proof of concept demonstration of interaction-free quantum electron microscopy.
