Abstract: A thin film semiconductor in the form of a metal semiconductor field effect transistor, includes a substrate 10 of paper sheet material and a number of thin film active inorganic layers that are deposited in layers on the substrate. The active layers are printed using an offset lithography printing process. A first active layer comprises source 12.1 and drain 12.2 conductors of colloidal silver ink, that are printed directly onto the paper substrate. A second active layer is an intrinsic semiconductor layer 14 of colloidal nanocrystalline silicon ink which is printed onto the first layer. A third active layer comprises a metallic conductor 16 of colloidal silver which is printed onto the second layer to form a gate electrode. This invention extends to other thin film semiconductors such as photovoltaic cells and to a method of manufacturing semiconductors.

Abstract: Apparatus for depositing ink on a substrate includes a nozzle defining an outlet for the ink, with at least a portion of the nozzle being electrically conductive. A first voltage source applies a first potential to the outlet nozzle. One or more auxiliary electrodes are located adjacent the outlet nozzle, and a second voltage source applies a second potential to the auxiliary electrodes. The apparatus includes a piezo-electric or thermal actuator for expelling ink from the nozzle towards a target zone on a substrate, the ink comprising a liquid vehicle and pigment particles dispersed in the vehicle. At least the pigment particles are electrically charged, typically due to the applied potentials. In one embodiment, an auxiliary electrode is disposed coaxially around the electrode formed by the nozzle. In another embodiment, an auxiliary electrode located beyond the nozzle, on a common axis with the electrode formed by the nozzle. The configuration of the nozzle, the auxiliary electrodes, and the values of the first and second potentials are selected to cause pigment particles to be concentrated in the target zone, so that a quantity of the pigment particles is deposited in the target zone having a higher concentration than the concentration of the pigment particles in the ink. The invention extends to a method of depositing ink on a substrate.

Abstract: A method is provided of producing inorganic semiconducting nanoparticles having a stable surface. The method comprises providing an inorganic bulk semiconductor material, such as silicon or germanium, and milling the bulk semiconductor material in the presence of a selected reducing agent. The reducing agent acts to chemically reduce oxides of one or more component elements of the semiconductor material, or prevent the formation of such oxides by being preferentially oxidised, thereby to provide semiconducting nanoparticles having a stable surface which allows electrical contact between the nanoparticles. The milling may take place in a mill in which the milling media and/or one or more components of the mill comprise the selected reducing agent. For example, the milling can be carried out in a high energy mill with a hammer action in which a pestle of the mill, a mortar of the mill, or both are composed of the selected reducing agent, or a low energy, stirred media mill, such as a ball mill, a rod mill or similar, in which the milling media, a lining of the mill, or both are composed of the reducing agent. The milling media or mill are typically composed of a metal selected from the group comprising iron, chromium, cobalt, nickel, tin, titanium, tungsten, vanadium, and aluminium, or an alloy containing one or more of said metals. In another embodiment of the method, the selected reducing agent comprises a liquid contained in the mill during milling of the bulk semiconductor material. The liquid is typically an acidic solution containing any of hydrochloric, sulphuric, nitric, acetic, formic, or carbonic acid, or a mixture thereof. The invention extends to a mill for carrying out the method.
