Abstract: A nanotip, is fabricated by modifying a precursor nanotip having an apex and a shank by applying an electric field in the presence of a reactive gas to perform field-assisted etching wherein atoms are preferentially removed from the shank by chemical interaction with the reactive gas, and controlling the reactive gas pressure and/or tip voltage to vary the electric field so as to promote field evaporation of apex atoms during fabrication of the nanotip and thereby control the overall profile of the resulting nano-tip. The method permits shaping of the overall tip profile.

Abstract: A new set of branched nanowire or nanotree structures and their fabrication process. Some structures have one or more of the following distinctions from other branched nanowires: (1) the trunk and branch diameter and branching number density can be changed along the trunk's length; (2) the branch's azimuthal direction can be controlled along the trunk's length; (3) the branch's diameter can be modulated along its length; (4) the crystal orientation and branches of the ensemble of nanowires can be aligned on a non-epitaxially matched substrate. The structures are made by a geometrically controlled kinetic growth method.

Abstract: There is described a pixel sensor converter for an image sensor array. In particular, a pixel sensor converter comprising: a delta-sigma converter comprising a modulator and a decimator. In some examples, the modulator is configured to be in communication with a detector, such as a photo-detector, and is configured to sample an analogue signal received from a detector at a particular sampling rate. The modulator is further configured to provide a bit stream of a particular bit rate. The provided bit stream corresponds to a sampled analogue signal. The decimator is in communication with the modulator, and is configured to receive and modify a bit stream provided from the modulator in order to provide a digital output signal. The provided digital output signal is representative of an analogue signal received at the modulator, but having a reduced bit rate than a corresponding bit stream provided by the modulator.
