Molecular switch for controlling color and fluorescence

A collaboration of researchers from Kumamoto, Yamaguchi, and Osaka Universities in Japan have discovered a new method of drastically changing the color and fluorescence of a particular compound using only oxygen (O2) and ...

Building blocks for GaN power switches

A team of engineers from Cornell University, the University of Notre Dame and the semiconductor company IQE has created gallium nitride (GaN) power diodes capable of serving as the building blocks for future GaN power switches—with ...

Solving an organic semiconductor mystery

Organic semiconductors are prized for light emitting diodes (LEDs), field effect transistors (FETs) and photovoltaic cells. As they can be printed from solution, they provide a highly scalable, cost-effective alternative ...

Kinetic battery chargers get a boost

New technology to capture the kinetic energy of our everyday movements, such as walking, and to convert it into electrical energy has come a step closer thanks to research to be published in the International Journal Biomechatronics ...

Moving towards electronically active threads

We are just starting to develop smart textiles. So far the problem has always been that it was not possible to apply the electronic components, called organic semiconductors, to three-dimensional structures such as fibres ...

Copper, gold and tin for efficient chips

With gold, copper or tin and special galvanizing processes, scientists are improving the function of semi-conductors and making the manufacture of microelectronic systems a child's play. Especially the LED industry could ...

Researchers grow semiconductors on graphene

Researchers at the Norwegian University of Science and Technology (NTNU) have patented and are commercializing GaAs nanowires grown on graphene, a hybrid material with competitive properties. Semiconductors grown on graphene ...
