Scientists grow organic semiconductor crystals vertically for first time

Breakthrough could literally reshape solar cells and electronic devices.

Nanocellulose materials by design

New computational approach allows researchers to design cellulose nanocomposites with optimal properties.

Graphene as a front contact for silicon-perovskite tandem solar cells

Researchers develop elegant process for coating fragile perovskite layers with graphene for the first time. Subsequent measurements show that the graphene layer is an ideal front contact in several respects.

Spin lifetime of electrons in graphene increased by magnetic fields

New research shows that applying a moderate in-plane magnetic field increases spin lifetime of electrons in graphene. The results of this work have profound implications for graphene's use as post-CMOS platform in spintronics, and make an important contribution to the understanding of physics of 2D materials.

Printable electronics thanks to contactless liquid deposition

Scientists have developed a technology for contactless deposition of liquids at nanoscale. In doing so, they make use of an electric field. Their technology will lead to new 3D-applications and can be of great value to, for example, cell research, nano-lithography and printable electronics.

Horizontal magnetic tunneling in a field-effect device integrated on silicon

The choice for energy-efficient technologies is not a matter of price choice but it is slowly turning into a matter of heat. A recent work suggests devices fabricated directly on Silicon with magnetic tunnel junctions governed by electric pulses, which means without current and minimizing the problem of overheating.

A necklace of fractional vortices

Researchers have arrived at how what is known as time-reversal symmetry can break in one class of superconducting material.
