organic plastic memory

Source reports about the development of Singapore scientists, directed toward the creation of new memory instrument . At its basis will be the use of gold nanos-particle and organic semiconductor composition by the name pentacene (pentacene). As is asserted, the combination is indicated key step to the side of the creation of organic plastic memory, which can prove to be cheaper and more universal, than silicic.

The created instrument has laminar structure. By way of enumeration from top to bottom, it consists in gold electrode, layer pentacene, gold nanos-particle, layer compound, which helps to nanos-particle to be retained on the lower layer, and lower layer - second electrode, which consists in silicon and dioxide silicon.

Gold nanos-particle serve for storing the electric charge of the fulfillment of key function retention information. Nanos-particle by diameter from three to five nanometers they are located in one layer and they are fixed I will pour off citric acid.

In order to ascertain that the received sandwich works as memory, scientists investigated its reaction to the accompanying volatge. The analogous structure, which does not contain the layer of gold nanos-particle, was used as the control model.

The results of measurements showed that the control model does not preserve charge. But here sandwich with the gold nanos-particle behaved differently: under the action of negative voltage, the positively charged zones, called holes, penetrated pentacene, after which proved to be those seized by the layer of nanos-particle. Applying a positive tension, scientists attained the release holes conversely.

In the opinion of participants in the project, the approach used by them, in view of its simplicity in the development and production, can lead to the appearance of new, cheaper and more universal memory. Work is the part of program, named polymeric and molecular electronics and instruments (Polymer and Molecular electronics and Devices, PMED), which carry out together the agency through the science, the technology and studies (Agency for science, Technology and Research, A * STAR) a
