Abstract: A method of making an array of sensor pixels, the method comprising: forming an array of nucleation sites on a growth substrate, each nucleation site configured to facilitate the growth of a respective domain of channel material on the growth substrate, the array of nucleation sites having a predefined configuration corresponding to an arrangement of pixel regions on a target substrate; growing an array of domains of channel material on the growth substrate from the array of respective nucleation sites to form a layer of channel material; and transferring the layer of channel material onto the target substrate such that the domains of channel material are substantially aligned with the pixel regions of the target substrate to allow the formation of a pixel array, each pixel of the array comprising source and drain electrodes configured to enable a flow of electrical current through a respective domain of channel material, and a functionalising material on the domain of channel material configured to produce a detectable change in the flow of electrical current on exposure to a physical stimulus which is indicative of one or more of the presence and magnitude of the physical stimulus.

Abstract: A method and apparatus, the method comprising: depositing (11) a quantum dot solution (23) onto a first substrate (21); solidifying (13) the quantum dot solution (23) on the first substrate (21) to form a solid layer (25) of quantum dots; arranging (15) the first substrate (21) overlaying a second substrate (27) so that an electrical connection is established between the solid layer (25) of quantum dots and one or more electrical components on the second substrate (27).

Abstract: A method comprising: depositing a quantum dot solution onto a supporting substrate in a drop-wise manner to form one or more discrete droplets on a surface of the substrate, the quantum dot solution and discrete droplets comprising a plurality of quantum dots having primary ligands attached thereto to stabilise the quantum dots in solution; and depositing a ligand-exchange solution onto the one or more discrete droplets in a drop-wise manner to cause replacement of the primary ligands attached to the plurality of quantum dots with shorter-chain secondary ligands, replacement of the primary ligands with the secondary ligands allowing the plurality of quantum dots within each discrete droplet to become sufficiently close packed to facilitate charge transfer there between.
