    Arif, Mohammad, 1974-; Yang, K.; Li, L.; Yu, Ping, Ph. D.; Guha, Suchi; Gangopadhyay, Shubhra; Förster, M.; Scherf, Ullrich (American Institute of Physics, 2009-02-13)
    Triplet enhanced ladder-type poly (para-phenylene) polymer (PhLPPP) with covalently bound trace amounts of palladium blended with a fullerene derivative [[6,6]-phenyl C61-butyric acid methyl ester (PCBM)] shows power ...
  • Sub-2 nm Size-Tunable High-Density Pt Nanoparticle Embedded Nonvolatile Memory 

    Yun, Minseong, 1978-; Mueller, David W.; Hossain, Maruf; Misra, Veena; Gangopadhyay, Shubhra (Institute of Electrical and Electronics Engineers, 2009-12)
    The charge-storage characteristics of a metal-oxide-semiconductor (MOS) structure containing size-tunable sub-2 nm Pt nanoparticles (NPs) between Al2O3 tunneling and capping oxide layers were studied. Significantly different ...
  • Supercritical CO2 extraction of porogen phase: An alternative route to nanoporous dielectrics 

    Lubguban, J. A.; Gangopadhyay, Shubhra (Materials Research Society, 2004-11)
    We present a supercritical CO2 (SCCO2) process for the preparation of nanoporous organosilicate thin films for ultralow dielectric constant materials. The porous structure was generated by SCCO2 extraction of a sacrificial ...
