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 ).

Claim (Index 30):
A method comprising:\n forming an inner core comprising a dielectric material; forming a first coating layer overlaying at least part of the inner core; forming a second coating layer overlaying the first coating layer where the second coating layer comprises a semi-conductor material; and wherein the first coating layer comprises a plasmonic material configured to enable surface plasmons to be generated at a boundary between the inner core and the first coating layer and a boundary between the first coating layer and the second coating layer and wherein the inner core, first coating layer and second coating layer form a composite particle.
