Presentation Transcript

  1. Multi-level Behavior, Material Scalability and Energy Efficiency of 1-D Phase-Change NanostructuresBin Yu, SUNY at Albany, DMR 1005793 Phase-switching chalcogenides play important role in the realization of future-generation ultra-high-capacity information storage and processing. In ultra-miniaturized information systems, material scalability and energy-efficiency are among critical considerations. Thin-film ternary chalcogenide (Ge2Se2Te5) has been primarily used as the dominant material platform for PCRAM. However, power-dissipation and material scalability at deeply scaled dimensions remain key challenges. We have demonstrated CVD-based chemical assembly of two selected types of binary chalcogenidenanowires (In2Se3 and GeTe) which have anticipated potential to be highly functional at nanoscale dimensions. The adjacent figure shows the fabricated structure for characterizing and exploring material response (phase transition) of binary chalcogenidenanowires to various external electrical stimulus.

  2. Multi-level Behavior, Material Scalability and Energy Efficiency of 1-D Phase-Change Nanostructures Bin Yu, SUNY at Albany, DMR 1005793 Team-based research efforts are being made with close collaboration between SUNY Albany and International SEMATECH Corp. SEMATECH is a semiconductor industry consortium developing future-generation chip technology for global semiconductor industry with its new headquarter recently relocated to Albany, NY. Faculty PI, graduate student and SEMATECH research engineers are working together to characterize key properties of nanoscale chalcogenide structures, including the influence of external electrical stimulation, material configuration, and critical physical dimensions. University/Industry Collaboration - Albany Nanotech complex includes research facilities of International SEMATECH. Faculty PI and graduate student are working closely with SEMATECH engineers to understand basic material behavior of chemically assembled phase-change binary chalcogenide nanowires at ultra-scaled physical dimensions.
