• A high-resolution polarimeter formed from inexpensive optical parts 

      Harvie, Andrew J.; Phillips, TW; De Mello, John Christian (Peer reviewed; Journal article, 2020)
      We describe a high resolution laser polarimeter built from commodity optical components. The optical rotation angle is determined by measuring the phase difference between two harmonically modulated polarised laser beams ...
    • Massively Parallel Arrays of Size-Controlled Metallic Nanogaps with Gap-Widths Down to the Sub-3-nm Level 

      Luo, Sihai; Mancini, Andrea; Berte, Rodrigo; Hoff, Bård Helge; Maier, Stefan; De Mello, John Christian (Peer reviewed; Journal article, 2021)
      Metallic nanogaps (MNGs) are fundamental components of nanoscale photonic and electronic devices. However, the lack of reproducible, high-yield fabrication methods with nanometric control over the gap-size has hindered ...
    • Prediction of Absorption Spectrum Shifts in Dyes Adsorbed on Titania 

      Venkatraman, Vishwesh; Yemene, Amsalu Efrem; De Mello, John Christian (Journal article; Peer reviewed, 2019)
      Dye adsorption on metal-oxide films often results in small to substantial absorption shifts relative to the solution phase, with undesirable consequences for the performance of dye-sensitized solar cells and optical sensors. ...
    • Spontaneous Formation of Nanogap Electrodes by Self‐Peeling Adhesion Lithography 

      Luo, Sihai; Hoff, Bård Helge; De Mello, John Christian (Journal article; Peer reviewed, 2019)
      Adhesion lithography (“a‐lith”) is a simple method for forming nanoscale gaps between dissimilar metals. In its usual form, a metal is patterned on a substrate, and conformally coated with an alkyl‐functionalized self‐assembled ...
