Nanotech Congress Gauges Advancements, Needs

Abstract:
The Fourth International Congress of Nanotechnology and Clean Tech Congress 2007, organized by the International Association of Nanotechnology (IANANO, San Jose), opened in San Francisco this week, offering a number of presentations on leading-edge developments in several of nanotech's varied fields, including electronics, medicine and biology.

Professor Miloslav Frumar, head of the research center at the University of Pardubice (Czech Republic), described in "Nanosize Films for High-Capacity Phase-Change Memories" the application of 5-50 nm films for phase-change memories (PCMs). He described how light or electrical pulses are used to change the state of these films from amorphous to crystalline and back again. Both states have different reflectivity parameters or electrical conductivity, and have been used for optical and electrical data storage. The nanothickness of the films for PCM materials sandwiched between isolation and contact layers allows fast heating and cooling (1011 K/sec). The amorphization and crystallization are quick — only a few nanoseconds or tens of nanoseconds — allowing high rates of writing or erasing. The effort described was based on pure and doped tellurides in the fourth and fifth groups of the periodic table of elements.
