    • Detecting Single Stranded DNA with a Solid State Nanopore 

      Fologea, Daniel; Gershow, Marc; Ledden, Bradley; McNabb, David S.; Golovchenko, Jene Andrew; Li, Jiali (American Chemical Society (ACS), 2005)
      Voltage biased solid-state nanopores are used to detect and characterize individual single stranded DNA molecules of fixed micrometer length by operating a nanopore detector at pH values greater than ∼11.6. The distribution ...

    • DNA molecules and configurations in a solid-state nanopore microscope 

      Li, Jiali; Gershow, Marc; Stein, Derek; Brandin, Eric Richard; Golovchenko, Jene Andrew (Nature Publishing Group, 2003)
      A nanometre scale pore in a solid state membrane provides a new way to electronically probe the structure of single linear polymers, including those of biological interest in their native environments. Previous work with ...

    • Feedback-controlled ion beam sculpting apparatus 

      Stein, Derek M.; McMullan, Ciaran J.; Li, Jiali; Golovchenko, Jene Andrew (AIP Publishing, 2004)
      We report the design of an “ion sculpting” instrument that enables the controlled fabrication of nanometer-sized structures in solid-state materials. The instrument employs a beam of kilo-electron-volt argon ions that ...

    • Ion-Beam Sculpting Time Scales 

      Stein, Derek; Li, Jiali; Golovchenko, Jene Andrew (American Physical Society (APS), 2002)
      A study of ion sculpting dynamics in SiO2 and SiN using periodically pulsed ion beams reveals material transport that depends strongly on the time structure of the pulsed beams. It is found that significant nanoscale matter ...

    • Nanopore Fabrication in Amorphous Si: Viscous Flow Model and Comparison to Experiment 

      George, H. Bola; Tang, Yuye; Chen, Xi; Li, Jiali; Hutchinson, John W.; Golovchenko, Jene A.; Aziz, Michael J. (American Institute of Physics, 2010)
      Nanopores fabricated in free-standing amorphous silicon thin films were observed to close under 3 keV argon ion irradiation. The closing rate, measured in situ, exhibited a memory effect: at the same instantaneous radius, ...
