Recent Publication(s)
  • "Electron Tunneling Induced Periodic Nucleation and Growth of Nanoparticles: Physical Basis of Chemical Reduction"

Chen F, You HJ, Yang SC, et al., Crystal Growth & Design 11(9): 3707-3712 Sep 2011. We have developed a periodic nucleation and growth mechanism for nanopartide-aggregated structure based on electron tunneling process that occurs in chemical replacement reactions.

  • "Synthesis, assembly and applications of semiconductor nanomembranes"

Rogers JA, Lagally MG, Nuzzo RG, Nature 477(7362) 45-53 Sep 2011. Research in electronic nanomaterials, historically dominated by studies of nanocrystals/fullerenes and nanowires/nanotubes, now incorporates a growing focus on sheets with nanoscale thicknesses, referred to as nanomembranes.

  • "Symmetry in Strain Engineering of Nanomembranes: Making New Strained Materials"

Scott SA, Savage DE, Celler GK, ACS Nano 5(7): 5532-5542 Jul 2011. We show that we can controllably tune the amount of strain and the asymmetry of the strain distribution In elastically isotropic and anisotropic materials uniformly over large areas.

  • "Defect-Free Single-Crystal SiGe: A New Material from Nanomembrane Strain Engineering"

Tanto B, Savage DE, Lagally MG, ACS Nano 5(7): 5814-5822 Jul 2011. Using nanomembrane strain engineering methods, we demonstrate the fabrication of fully elastically relaxed Si(1-x)Ge(x) nanomembranes (NMs) for use as growth substrates for new materials.
