Development of Novel Material with Reversible Photochromism Characteristics, Paving the way for Next Generation Ultrahigh-Density Memories and Displays

February 9, 2011 · Filed Under Trendy Products · 1 Comment 

Inorganic Photochromic materials has been considered for quite sometimes as an ideal candidate in manufacturing the next generation high-density memories as well as displays, due to their responsiveness to visible light for manufacture high capacity memories by using semiconductor laser or LED as its light source. But most inorganic materials do not exhibit photochromic response to visible light, plus they have a low durability, or even worse they show a slow color change and poor color reversibility (i.e. failed to decolorize after being irradiated several times.). Furthermore, the color of most of these materials was blue. In repose to overcome these inherent difficulties, group of researchers at AIST in Japan has developed a composite metal oxide materials that has a stable and reversible phtochromism when it is irradiated alternately with blue and green monochromatic lights.

Development of Novel Material for use in Involatile Phase-Change Random Access Memory

November 30, 2010 · Filed Under Green Tech, Trendy Products · 1 Comment 

Group of Japanese researchers at Tohoku University has successfully developed materials for Ge-Cu-Te phase-change random access memories (PCRAM) featuring a high thermal stability and a low melting point. The new development was with an aim to resolve such problem as data loss under the environment at high temperature, helping to save data for period of ten years under the environment at more than 125 degrees Celsius. In addition to this the new material will help to reduce power consumption for data rewiring. Read more
