Scientists from Purdue University have created a new class of electrically conductive polymers known as PTMA which are likely to revolutionise the manufacture of smart lightweight batteries, ultrathin antiglare coatings and transparent solar cells for the aircraft and electronics markets in a relatively inexpensive manner.
The Royal Swedish Academy of Sciences has awarded the Nobel Prize in Physics for 2014 to the inventors of a new eco-friendly, energy-efficient light source – the blue light-emitting diode (LED).
An increase in the conductivity of semiconductors such as silicon present in solar cells and computer chips, in the presence of light is a widely accepted principle. MIT researchers have invented a distinct two-dimensional semiconductor which acts as a poor conductor under illumination. The semiconductor is made of a single molybdenum disulfide (MoS2) layer, as thick as three atoms.
A research team from The University of Texas have produced a breakthrough technology in the field of wearable computers with self-sufficient power sources. More immediately this could be used in smartphones to extend their battery life.
A team of researchers has analyzed a new approach for tuning of gallium arsenide (GaAs). This material possesses natural semiconducting properties. The nanoparticle and nanowire form of GaAs can be used in applications where silicon is being presently used, such as in the manufacture of optoelectronics and solar cells.
Engineers at the University of Utah have found a new way to produce “topological insulators”, which possess a large energy gap. This study has been led by Feng Liu, a materials science and engineering professor, at the University of Utah. Topological insulators could help develop superfast computers that do not get over heated when performing hi-speed calculations.
University of Massachusetts, Amherst researchers have designed a light-weight, highly efficient and easily processable solar cell that can use almost any metal as the electrode, successfully impairing the so-called ‘electrode barrier’.
University of Arkansas engineers have developed as a new semiconductor material that holds promise for cost-effective photodetectors used in production of infrared cameras for smartphones. This material comprises of a silicon substrate on which layers of germanium tin are deposited.
A highly efficient spin-charge converter has been created by a group of researchers at Institute of Physics at Johannes Gutenberg University Mainz (JGU) using gallium-arsenide (GaAs), a common semiconductor material.
University of Notre Dame researchers have studied the basic optical properties of organic-inorganic "hybrid" perovskites, a new class of semiconducting materials. The study results are published in the journal, Nature Photonics.
