Abstract: A composite nanoparticle (1) comprises an inner core (3) made of a transparent dielectric material, a first coating layer (5) made of a plasmonic material which overlays the inner core (3) and a second coating layer (7) made of a semiconductor material overlaying the first coating layer (5). Incident light is absorbed by generating surface plasmons at a boundary (4) between the inner core (3) and the first coating layer (5) and at a boundary (6) between the first coating layer (5) and the second coating layer (7) in order to increase the light absorption and thus the exciton generation by the second coating layer (7). The structure of composite particle (1) also allows for tuning of the resonance of the surface plasmons which tunes the frequency of light, or other electromagnetic radiation, that is detected. A photodetector for detecting the absorbed light comprises a channel (25) which is a layer of a two-dimensional material between a source electrode (23) and a drain electrode (24), and a layer (27) of a plurality of composite particles (1). The layer (27) acts as a photogate of the field effect transistor (21).

Abstract: A device for direct X-ray detection (516) comprises a plurality of substantially parallel conductive channels (501) separated from one another by a quantum dot material (510), thereby forming a composite material layer (517). The parallel conductive channels (501) are electrically connected to source and drain electrodes (503 504a) which enable a flow of electrical current through the conductive channels (501). The quantum dot material (510) generates electron hole pairs upon exposure to incident electromagnetic radiation and the thus generated charge results in an electric field which causes a change in electrical current passing through at least one of the conductive channels (501). The change in electrical current is indicative of one or more of the presence and magnitude of the incident electromagnetic radiation. Since the conductive channels (501) are oriented in a direction perpendicular to the plane of the substrate (502), the distances between the conductive channels can be chosen under consideration of the diffusion lengths of the generated charge carriers and independently from the thickness of the composite material layer (517) required for X-ray radiation.

Abstract: A thin film manipulator comprising: a porous thin film manipulator interface with a chamber surface and an opposing thin film surface, the porous thin film manipulator interface having a through-thickness porosity to allow a fluid to be used to develop a pressure difference between the chamber surface and the opposing thin film surface; and a plurality of chambers positioned laterally across the chamber surface of the porous thin film manipulator interface, the plurality of chambers configured to allow: progressive removal of fluid laterally across the interface to provide a lateral pressure gradient which progressively decreases the pressure laterally across the thin film surface to progressively hold a thin film at the thin film surface and/or progressive application of fluid laterally across the interface to provide a lateral pressure gradient which progressively increases the pressure laterally across the thin film surface to progressively release an adhered thin film from the thin film surface.
