    • Analysis of field-emission from a diamond-metal-vacuum triple junction 

      Sun, Sheng; Ang, Ricky Lay Kee (2012)
      A quantitative electron tunneling model is constructed to calculate the electron emission from a diamond-metal-vacuum triple junction, including the effects of the field enhancement at the interface of the triple junction, ...
    • Analysis of nonuniform field emission from a sharp tip emitter of Lorentzian or hyperboloid shape 

      Sun, Sheng; Ang, Ricky Lay Kee (2013)
      For a sharp tip emitter, due to the non-uniform emission feature and the electron beam expansion in the vacuum, it is difficult to precisely determine the average field enhancement factor β_c as well as the effective ...
    • Downhole pipe selection and arrangement for acoustic drillstring telemetry 

      Kumar, L. S.; Han, W. K.; Guan, Yong Liang; Lee, Y. H.; Sun, Sheng; Arasu, Muthukumaraswamy Annamalai; Je, Minkyu (2011)
      Drillstring acoustic telemetry is an effective transmission method to retrieve downhole data. In this paper, finite-difference algorithm is used for acoustic wave propagation prediction along the drillstring. An impulse ...
    • Genus-Wide Comparative Genomics of Malassezia Delineates Its Phylogeny, Physiology, and Niche Adaptation on Human Skin 

      Wu, Guangxi; Zhao, He; Li, Chenhao; Rajapakse, Menaka Priyadarsani; Wong, Wing Cheong; Xu, Jun; Saunders, Charles W.; Reeder, Nancy L.; Reilman, Raymond A.; Scheynius, Annika; Sun, Sheng; Billmyre, Blake Robert; Li, Wenjun; Averette, Anna Floyd; Mieczkowski, Piotr; Heitman, Joseph; Theelen, Bart; Schröder, Markus S.; De Sessions, Paola Florez; Butler, Geraldine; Maurer-Stroh, Sebastian; Boekhout, Teun; Nagarajan, Niranjan; Dawson, Thomas L. (2015)
      Malassezia is a unique lipophilic genus in class Malasseziomycetes in Ustilaginomycotina, (Basidiomycota, fungi) that otherwise consists almost exclusively of plant pathogens. Malassezia are typically isolated from ...
    • Onset of space charge limited current for field emission from a single sharp tip 

      Sun, Sheng; Ang, Ricky Lay Kee (2012)
      A protrusive model of the Child-Langmuir (CL) law is proposed for non-uniform electron field emission from a sharp tip of either Lorentzian or hyperboloid shape. The model is expressed as Jc = μ×J1D at large electric field ...
    • Shot noise of low energy electron field emission due to Klein tunneling 

      Sun, Sheng; Ang, Ricky Lay Kee (2012)
      This paper investigates the property of shot noise for low energy electron field emission from a single-layer vertically aligned graphene sheet assuming the emission process is due to Klein tunneling. In our model, we use ...
