When predictions of theoretical chemists become reality

Making 2D Topological Polymers a reality

26-May-2020

Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological ...

Neural Hardware for Image Recognition in Nanoseconds

Ultra-fast image sensor with a built-in neural network can be trained to recognize certain objects

06-Mar-2020

Automatic image recognition is widely used today: There are computer programs that can reliably diagnose skin cancer, navigate self-driving cars, or control robots. Up to now, all this has been based on the evaluation of image data as delivered by normal cameras - and that is time-consuming. ...

2D materials: arrangement of atoms measured in silicene

03-Jan-2020

Silicene consists of a single layer of silicon atoms. In contrast to the ultra-flat material graphene, which is made of carbon, silicene shows surface irregularities that influence its electronic properties. Now, physicists from the University of Basel have been able to precisely determine this ...

Solving the Mystery of Quantum Light in Thin Layers

17-Oct-2019

A very special kind of light is emitted by tungsten diselenide layers. The reason for this has been unclear. Now an explanation has been found at TU Wien (Vienna). It is an exotic phenomenon that nobody was able to explain for years: when energy is supplied to a thin layer of the material ...

Bottom-up Synthesis of Crystalline 2D Polymers

A Dream Finally Comes True

27-Sep-2019

Scientists at the Center for Advancing Electronics Dresden (cfaed) at TU Dresden have succeeded in synthesizing sheet-like 2D polymers by a bottom-up process for the first time. A novel synthetic reaction route was developed for this purpose. The 2D polymers consist of only a few single atomic ...

Unprecedented insight into two-dimensional magnets using diamond quantum sensors

29-Apr-2019

For the first time, physicists at the University of Basel have succeeded in measuring the magnetic properties of atomically thin van der Waals materials on the nanoscale. They used diamond quantum sensors to determine the strength of the magnetization of individual atomic layers of the material ...

New record on the growth of graphene single crystals

04-Apr-2019

Graphene, especially the graphene single crystal is a star material for the future photonics and electronics due to their unique properties, such as giant intrinsic charge carrier mobility, record thermal conductivity, super stiffness and excellent light transmission. However, whether graphene ...

Watching two-dimensional materials grow

30-Aug-2018

Atomically thin crystals will play an ever greater role in future – but how can their crystallisation process be controlled? A new method is now opening up new possibilities. They are among the thinnest structures on earth: “two dimensional materials” are crystals which consist of only one or a ...

Salt boosts creation of 2-D materials

23-Apr-2018

A dash of salt can simplify the creation of two-dimensional materials, and thanks to Rice University scientists, the reason is becoming clear. Boris Yakobson, a Rice professor of materials science and nanoengineering and of chemistry, was the go-to expert when a group of labs in Singapore, China, ...

A treasure trove for nanotechnology experts

08-Mar-2018

2D materials, which consist of a few layers of atoms, may well be the future of nanotechnology. They offer potential new applications and could be used in small, higher-performance and more energy-efficient devices. 2D materials were first discovered almost 15 years ago, but only a few dozen of ...
