Photorefractive Materials for Optical Storage and Display
Real -time data storage and processing using optical techniques have been considered in recent years. Of particular interest are photosensitive electro-optic crystals which permit volume storage in the form of phase holograms, by means of a charge transfer process. A survey of the state of the art of such holographic memories is presented. The physical mechanism responsible for the formation of...
متن کاملSustainable Materials for Sustainable Energy Storage: Organic Na Electrodes
In this review, we summarize research efforts to realize Na-based organic materials for novel battery chemistries. Na is a more abundant element than Li, thereby contributing to less costly materials with limited to no geopolitical constraints while organic electrode materials harvested from biomass resources provide the possibility of achieving renewable battery components with low environment...
متن کاملOptical data storage media
In this paper, we review many of the technical issues that must be addressed in developing high-quality optical disk recording media. The geometric design of tracking grooves and embossed data on the disk substrate must be optimized to the characteristics of the optical drive to support robust data seeking, track following, and data addressing. To ensure adequate recording performance and drive...
متن کاملOptical data storage
The distribution of audio information in disk format—sound stored as modulations in a flat surface—has had a long and successful track record. At first, analog signals were imprinted on shellac and then later vinyl platters. But recently, sound has been almost exclusively distributed as and replayed from digitally encoded data, molded into the surface of compact polymer disks. This migration wa...
متن کاملOptical transitions in new trends organic materials
The PTCDA (3,4,9,10-Perylene-tetracarboxylic dianhydride) and the NTCDA (1,4,5,8Naphtalenetetracarboxylic dianhydride) are aromatic, stable, planar and highly symmetric with unusual electrical properties. The PTCDA is a semiconductor organic crystalline of particular interest due to its excellent properties and electronic potential that are used in optoelectronic devices and the NTCDA it is mon...
