Motorized crystals

Unidirectional molecular motors can already perform tasks at the molecular scale, but in order to harness their properties at a larger scale, scientists are working to devise ways in which to make them work in a coordinated manner. Feringa and co-workers now show that they can embed molecular motors in the scaffold of a metal–organic framework (MOF) and that the rotation of the motor within the MOF crystals in unhindered. The cover image is a microscopy picture of MOF crystals that contain molecular motors in their structure.

    Until recently, the family of 2D materials was missing one crucial member — 2D magnets. This Review presents an overview of the 2D magnets studied so far and of the heterostructures that can be realized by combining them with other 2D materials.

    While neutral-charge quantum dots in optically active WSe2 do not show spin-valley initialization, localized holes possess a net spin and their spin-valley state can be selected with the helicity of the laser excitation.

    Under the application of a magnetic field, the 2D electron gas in a gated MoS2 monolayer becomes spin-polarized, the Coulomb interaction probably being key to the symmetry breaking.

    Instead of using capacitively coupled charge sensors, which imply additional complexity in the device architecture, radiofrequency reflectometry on the gate defining the quantum dot can read out the spin state of a double quantum dot in a single shot.

    Gate-tuning of a Fermi reservoir enables the deterministic loading of single electrons or holes into a localized quantum dot in a WSe2 monolayer and the observation of hybrid excitons originating from strong, spin-conserving tunnelling between the dot and the reservoir.
