Abstract: The invention provides a detector comprising a metamaterial absorber and a micro-bolometer arranged to detect terahertz (THz) radiation. The metamaterial absorber can absorb multiple frequency bands, from the infrared and the THz regions of the electromagnetic spectrum. The detector is scalable to be suitable for use in a focal plane array.The invention also provides a hybrid of a plasmonic filter, e.g. for optical radiation, and a metamaterial absorber for terahertz (and/or infrared) radiation, to create a single material capable of absorbing narrow band terahertz radiation and filtering radiation in another part of the spectrum, e.g. optical radiation. Such material has great potential in future imaging technology where hybridization can maximize the spectral information density of an optical system.

Abstract: A CMOS-based chip having multiple sensing modalities that are able independently to detect multiple metabolites present in a sample. In particular, the chip provides multiple sensing modalities capable of performing detection within the same physical test volume, i.e. the chip can simultaneously detect a plurality of chemical reactions occurring in the test volume, where each chemical reaction yields a result that is independently detectable. The chip may comprise an optical sensor (e.g. photodiode) and a chemical sensor (e.g. pH sensor, embodied as an ISFET). With this technique, multiple metabolites may be measured in real time using a small scale point-of-care device.

Abstract: A method of fabricating a field-effect transistor in which a native oxide layer is removed prior to etching a gate recess. The cleaning step ensures that the etch of the gate recess starts at the same time across an entire sample, such that a uniform gate recess depth and profile can be achieved across an array of field-effect transistors. This results in a highly uniform switch-off voltage for the field-effect transistors in the array.
