Summary: TEHRAN (FNA)- Hybrid organic-inorganic perovskites have been used in optoelectronic devices
including solar cells, photodetectors, light-emitting diodes and lasers, but the surface of hybrid perovskites is prone to surface defects, where charge carriers are trapped in the semiconducting material.
They signed a Memorandum of Understanding (MoU) for joint efforts in several areas including renewable energy technology, nanomaterials and nanofabrication, optoelectronic devices
and integration and green environment.
These defects act as non-radiative trap states, producing heat instead of light --so removing or passivating these defects is an important step towards high-efficiency optoelectronic devices
Massive advances in portable imaging systems and optoelectronic devices
are further anticipated to keep the growth pace uniform, owing to their superlative functional attributes such as high resolution imaging compatible with diverse electronic devices such as wide-angle cameras.
He said, "Currently, we are making use of the comprehensive properties of the material to make novel optoelectronic devices
, which could be utilised in many new human-machine communication interfaces." (ANI)
Silanna is using the GEN10 system for advanced oxide research and development for optoelectronic devices
. The company also operates a Veeco Dual GEN200 MBE system for production of advanced nitride compound semiconductor devices, including ultraviolet LEDs.
The three chapters introduce the basics of scanning near-field optical microscopy, one-dimensional nanofibers and nanowires for developing nanoscale photonic circuits, and photonic crystals for use in passive photonic devices and active optoelectronic devices
. Black and white illustrations are provided.
With the rapid development of optoelectronic technology, optoelectronic devices
have entered the nano era [1, 2], and many nanotechnology has been used in silicon photonics [3-5].
Although this method is demonstrated with 40[micro]m diameter solder beads arranged with OET, it could be applied to a great range of discrete components from nanowires to optoelectronic devices
, thus overcoming one of the basic hurdles in using optical micromanipulation techniques in a manufacturing micro-assembly setting.
The new method can be used to optimise the performance of optoelectronic devices
such as organic solar cells, sensors and transistors.
Using their method of self-assembly, the researchers achieved precision and control over the material at an atomic level, making it potentially useful in a wide range of applications, "including fabrics that generate electricity, optoelectronic devices
that employ both electricity and light, and superconducting materials that conduct electricity without any loss."
