Researchers use electron microscope to turn carbon nanotube into tiny transistor
Dec 24, 2021 (Nanowerk News) An international team of researchers have used a unique tool inserted into an electron microscope to create a transistor that’s 25,000 smaller than the width of a human hair. The research, published in the journal Science ("Semiconductor nanochannels in metallic carbon nanotubes by thermomechanical chirality...
Carbon nanotube fibers stand strong
Dec 23, 2021 (Nanowerk News) Up here in the macro world, we all feel fatigue now and then. It’s the same for bundles of carbon nanotubes, no matter how perfect their individual components are. A Rice University study calculates how strains and stresses affect both “perfect” nanotubes and those assembled...
Novel semiconductor gives new perspective on Anomalous Hall Effect
Dec 23, 2021 (Nanowerk News) A large, unconventional anomalous Hall resistance in a new magnetic semiconductor in the absence of large-scale magnetic ordering has been demonstrated by Tokyo Tech materials scientists, validating a recent theoretical prediction. Their findings provide new insights into the anomalous Hall effect, a quantum phenomenon that...
Record-breaking hole mobility heralds a flexible future for electronics
Dec 23, 2021 (Nanowerk News) Technologists envisage an electronically interconnected future that will depend on cheap, lightweight, flexible devices. Efforts to optimize the semiconductor materials needed for these electronic devices are therefore necessary. Researchers from the University of Tsukuba have reported a record-breaking germanium (Ge) thin film on a plastic...
Tuning a magnetic fluid with an electric field creates controllable dissipative patterns
Dec 23, 2021 (Nanowerk News) Researchers at Aalto University have shown that a nanoparticle suspension can serve as a simple model for studying the formation of patterns and structures in more complicated non-equilibrium systems, such as living cells (Science Advances, "Electroferrofluids with nonequilibrium voltage-controlled magnetism, diffuse interfaces, and patterns"). The...
