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
They cover the synthesis and applications of two-dimensional transition metal dichalcogenides, two dimensional electron gas at interfaces between LaAlO3 and SrTiO3, multiferrorism and magneto-electric applications in bismuth ferrite, recent developments in resistive switching nanocrystalline thin films derived using solution processed techniques, zinc oxide thin films and nanostructures for acoustic wave-based microfluidic and sensing applications, diluted magnetic semiconducting
oxides, and first principles in exploring the magnetism of oxide-based diluted magnetic semiconductors.
They then used semiconducting
polymer materials to print photodiodes, which can convert light into electricity.
Professor Pavle Radovanovic of Waterloo says, "We've basically magnetized individual semiconducting
nanocrystals (tiny particles nearly 10,000 times smaller than the width of a human hair) with light at room temperature....
As-synthesized nanotubes represent a mixture of SWCNTs with metallic and semiconducting
conductivity type, which limits their applications .
An SWNT exhibits either metallic or semiconducting
characteristics depending on its chiral indices (n, m) .
In spite of their small dimensions, adjustable electronic characteristics for a metallic or semiconducting
conductivity are structure dependent.
The ZEBRA product is the first available platform solution for realizing next-generation semiconductor devices technologies using the novel material of semiconducting
single-walled carbon nanotubes (CNT).
Unfortunately, these expectations have not been met because there has been no efficient method of separating semiconducting
nanotubes--those suitable for use in transistors--from metallic nanotubes, which have a distinctively different set of characteristics.
QD materials are light-emitting or semiconducting
nanoparticle materials whose physical dimensions affect the band gap of the semiconducting
In this respect, two-dimensional gapless graphene and semiconducting
transition-metal dichalcogenides have emerged as promising candidates due to their atomic thickness and chemical stability.
