A method of coating a non-refractory and/or non-planar substrate () with synthetic diamond material using a microwave plasma chemical vapour deposition (CVD) synthesis technique, the method comprising: forming a composite substrate assembly () comprising: a support substrate () comprising an upper surface; one or more electrically conductive refractory guards () disposed over the upper surface of the support substrate and extending to a height habove the upper surface of the support substrate; and one or more non-refractory and/or non-planar substrates disposed over the upper surface of the support substrate and extending to a height habove the upper surface of the support substrate, wherein the height his less than the height h, wherein a difference in height h&#x2212;hlies in a range 0.2 mm to 10 mm; placing the composite substrate assembly within a plasma chamber of a microwave plasma CVD reactor; feeding process gases into the plasma chamber including a carbon containing gas and a hydrogen containing gas; feeding microwaves in the plasma chamber to form a microwave plasma at a location over the composite substrate assembly; and growing synthetic diamond material on the one or more non-refractory and/or non-planar substrates.

Method for making diamond layers by CVD

An electrode comprising an electrically conducting diamond plate wherein the diamond plate comprises at least one elongate aperture and having an aperture edge length per unit working area of the diamond plate of greater than about 4 mm/mm, electrolysis cells comprising such electrodes, methods of treating water using such electrolysis cells and a method of production of ozone are disclosed.

Diamond electrode

A radiation detector comprises a substrate of diamond material and at least one electrode formed at a surface of the substrate. The electrode comprises electrically conductive material deposited in a cavity in the surface of the substrate so that at least a portion of the material of the electrode is below the surface of the substrate. The cavity will typically be an elongate trench or channel in which electrically conductive material such as boron-doped diamond is deposited. In some embodiments, at least two electrodes are located adjacent to one another at the surface of the substrate. In other embodiments, the device has a plurality of electrodes, at least one of which is located at a first surface and at least one of which is located at an opposed second surface of the substrate. In the latter case, an electrode at one surface of the substrate can be connected to an electrode at the opposed surface of the substrate by means of a conductive via, which consists of a through-hole filled or coated with conductive material. Typically, the electrodes are arranged in an interdigitated configuration, each electrode having a plurality of elongate electrode elements. Each such electrode element extends parallel to at least one adjacent electrode element of another electrode.
