Hall effect becomes viscous in graphene

Researchers at The University of Manchester in the UK have discovered that the Hall effect—a phenomenon well known for more than a century—is no longer as universal as it was thought to be.

Colloidal quantum dots make LEDs shine bright in the infrared

The ideal optoelectronic semiconductor material would be a strong light emitter and an efficient charge conductor to allow for electrical injection in devices. These two conditions, when met, can lead to highly efficient ...

Multibit optoelectronic memory

NUS scientists have developed multibit optoelectronic memory using a heterostructure made of two-dimensional (2-D) materials for next generation devices.

Commercially relevant bismuth-based thin film processing

Developing materials suitable for use in optoelectronic devices is currently a very active area of research. The search for materials for use in photoelectric conversion elements has to be carried out in parallel with developing ...
