Spintronics by 'straintronics'

14 февраля, 2019 - 23:31
Data storage in magnetic media is very energy consuming. Novel materials could reduce the energy needed to control magnetic memories thus contributing to a smaller carbon footprint of the IT sector. Now an international team has observed at the HZB lightsource BESSY II a new phenomenon in iron nanograins: whereas normally the magnetic moments of the iron grains are disordered at room temperature, this can be changed by applying an electric field.

High-performance quantum dot mode-locked laser on silicon

13 февраля, 2019 - 21:22
Ten years into the future. That's about how far an electrical and computer engineering professor and his research team are reaching with the recent development of their mode-locked quantum dot lasers on silicon. It's technology that not only can massively increase the data transmission capacity of data centers, telecommunications companies and network hardware products to come, but do so with high stability, low noise and the energy efficiency of silicon photonics.

Customized mix of materials for three-dimensional micro- and nanostructures

13 февраля, 2019 - 18:04
Three-dimensional structures on the micrometer and nanometer scales have a great potential for many applications. An efficient and precise process to print such structures from different materials has now been presented: researchers have integrated a microfluidic chamber into a 3D laser lithography device. Then, they used this system to produce multi-colored, fluorescent security features to protect banknotes, documents, and branded products against counterfeiting.

Sensitive sensor detects Down syndrome DNA with blood test during pregnancy

13 февраля, 2019 - 16:16
According to the Centers for Disease Control and Prevention, Down syndrome is the most common birth defect, occurring once in every 700 births. However, traditional noninvasive prenatal tests for the condition are unreliable or carry risks for the mother and fetus. Now, researchers have developed a sensitive new biosensor that could someday be used to detect fetal Down syndrome DNA in pregnant women's blood.

Nano drops a million times smaller than a teardrop explodes 19th century theory

12 февраля, 2019 - 20:00
Droplets emanating from a molecular 'nano-tap' would behave very differently from those from a household tap 1 million times larger -- researchers have found. This is potentially crucial step for a number of emerging nano technologies, e.g., manufacture of nano-sized drug particles, lab-on-chip devices for in situ diagnostics, and 3D printers capable of nanoscale resolution.

Engineers develop room temperature, two-dimensional platform for quantum technology

11 февраля, 2019 - 22:00
Researchers have now demonstrated a new hardware platform based on isolated electron spins in a two-dimensional material. The electrons are trapped by defects in sheets of hexagonal boron nitride, a one-atom-thick semiconductor material, and the researchers were able to optically detect the system's quantum states.

First transport measurements reveal intriguing properties of germanene

7 февраля, 2019 - 21:24
Germanene is a 2D material that derives from germanium and is related to graphene. As it is not stable outside the vacuum chambers in which is it produced, no real measurements of its electronic properties have been made. Scientists have now managed to produce devices with stable germanene. The material is an insulator, and it becomes a semiconductor after moderate heating and a very good metallic conductor after stronger heating.
