Semiconductor nanochannels in metallic carbon nanotubes by thermomechanical chirality alteration


Abstract: "Carbon nanotubes have a helical structure wherein the chirality determines whether they are metallic or semiconducting. Using in situ transmission electron microscopy, we applied heating and mechanical strain to alter the local chirality and thereby control the electronic properties of individual single-wall carbon nanotubes. A transition trend toward a larger chiral angle region wa... » read more

Power/Performance Bits: Sept. 29


Implantable transmitter Researchers from Purdue University developed a fully implantable, wirelessly powered 2.4GHz radio-frequency transmitter chip for wireless sensor nodes and biomedical devices. The team says the transmitter chip consumes the lowest amount of energy per digital bit published to date, consuming an active-mode power of 70 μW at 10 Mbps while radiating -33 dBm of power, r... » read more

Power/Performance Bits: Mar. 11


Reading qubits faster Researchers at Aalto University and VTT Technical Research Centre of Finland propose a faster way to read information from qubits, the building blocks of quantum computers. Currently, they are extremely sensitive to disruption even in cryogenic environments, holding quantum information for less than a millisecond. In the method now used to read information from a qubit... » read more

Space elevators Last year, Pennsylvania State University disclosed a technology called benzene-derived carbon nanothreads or sometimes called diamond nanothreads (DNTs). DNTs resemble carbon nanotubes. They are tiny hollow cylindrical tubes that are stronger than steel, but they are also brittle. Basically, DNTs are 1D structures with poly-benzene sections, which are connected by Stone–Wa... » read more
