(Nanowerk Spotlight) Carbon nanotubes are attractive materials as the building block of quantum-dot based nanodevices. In particular, single-wall carbon nanotubes (SWCNTs) are interesting because they ...

Creating and controlling quantum dots via electrical methods, is likely to lead to new frontiers in the quest to develop stable and efficient qubits. Exploring how zinc oxide can be used in ...

How it works Schematic showing how a five-electron droplet (shown in blue) is transported inside the selected potential minimum of a SAW. Electrostatic gates (yellow) are used to guide the electron ...

The structure of the zinc oxide (ZnO) device. A two-dimensional electron gas (2DEG) forms at the (Mg, Zn)O/ZnO interface. By applying voltages to the gate electrodes, we can confine electrons in a ...
