The present invention relates to a method for forming nano-gaps in graphene. The method may include applying a voltage across a region of graphene such that a nano-gap which extends across the entire width of the graphene is formed, wherein the region across which the voltage is applied may include a point which is the narrowest in the region.

The present disclosure relates to novel memristive devices, uses thereof, and processes for their preparation. In a first aspect, the disclosure provides a quantum memristor, including a first quantum dot (QD) which is capacitively coupled to a second quantum dot (QD), a source electrode, a drain electrode, and a bath electrode, wherein the source electrode and the drain electrode are coupled via quantum tunneling to QDand the bath electrode is coupled via quantum tunneling to QD, and wherein QDis capacitively coupled to either the source electrode or the drain electrode.

An atomic clock comprises endohedral fullerene systems which provide the standard frequency oscillations. A magnet device applies a magnetic field to the endohedral fullerenes. The applied magnetic field is adjustable. An excitation device both excites each endohedral fullerene system to cause it to undergo transitions which generate the time-keeping oscillations, and also probes the systems such that the oscillations can be measured and the device controlled. A detection device senses the response of the systems induced by the excitation device. The output of the detection device is fed to a controller. The controller produces the atomic clock output, which is the clock signal or frequency standard, and also controls the magnet device and the excitation device. The controller controls the magnetic field applied by the magnet device such that the energy difference of the time-keeping transition is insensitive to variations in magnetic field, thereby stabilizing the frequency of the oscillations and avoiding the effects of changes in external magnetic field.

Atomic clock

An information register stores information represented by the states of endohedral fullerenes in a nanotube. Possible states are spin-states or morphological states, such as endohedral species having intrinsic or induced electric dipole moment or characteristic electric polarizility. The states of successive endohedral fullerenes along the nanotube are coupled by interaction mediated by electrons in the nanotube. The register can be used as part of a quantum computer or a classical computer.
