Breakthrough in organic electronics

A simple new tweak could double the efficiency of organic electronics

16-Jan-2019

The majority of our everyday electronics are based on inorganic semiconductors, such as silicon. Crucial to their function is a process called doping, which involves weaving impurities into the semiconductor to enhance its electrical conductivity. It is this that allows various components in ...

How to melt gold at room temperature

21-Nov-2018

When the tension rises, unexpected things can happen - not least when it comes to gold atoms. Researchers from, among others, Chalmers University of Technology, Sweden, have now managed, for the first time, to make the surface of a gold object melt at room temperature. Ludvig de Knoop, from ...

Graphene assembled film shows higher thermal conductivity than graphite film

26-Jun-2018

Researchers at Chalmers University of Technology, Sweden, have developed a graphene assembled film that has over 60 percent higher thermal conductivity than graphite film – despite the fact that graphite simply consists of many layers of graphene. The graphene film shows great potential as a ...

Unconventional superconductor may be used to create quantum computers of the future

21-Feb-2018

With their insensitivity to decoherence what are known as Majorana particles could become stable building blocks of a quantum computer. The problem is that they only occur under very special circumstances. Now researchers at Chalmers University of Technology have succeeded in manufacturing a ...

Graphene enables high-speed electronics on flexible materials

02-Nov-2017

A flexible detector for terahertz frequencies (1000 gigahertz) has been developed by Chalmers researchers using graphene transistors on plastic substrates. It is the first of its kind, and can extend the use of terahertz technology to applications that will require flexible electronics, such as ...

Electric cars can become more eco-friendly through life cycle assessment

13-Oct-2017

It is time to stop discussing whether electric cars are good or bad. Instead industry, authorities and policy-makers need to work together to make them as eco-friendly as possible. This is the view taken by Anders Nordelöf, a researcher at Chalmers University of Technology. In a recent thesis, he ...

Graphene and other carbon nanomaterials can replace scarce metals

20-Sep-2017

Scarce metals are found in a wide range of everyday objects around us. They are complicated to extract, difficult to recycle and so rare that several of them have become “conflict minerals” which can promote conflicts and oppression. A survey at Chalmers University of Technology now shows that ...
