Article Synopsis
- - The 4D Camera is a high-speed sensor designed for electron microscopy, capable of scanning at 87,000 Hz and generating data at approximately 480 Gbit/s, which is processed by specialized computers handling large datasets between 10-700 GB in size.
- - It features a back illuminated detector that can detect single electron events at voltages ranging from 30 to 300 kV, enabling efficient electron counting that compresses data size significantly (by 10-300 times).
- - The camera allows for rapid analysis through open-source processing algorithms, facilitating complex scanning diffraction experiments typically done in scanning transmission electron microscopy.
Laterally oriented single-crystal silicon nanowires are epitaxially grown between highly doped vertically oriented silicon electrodes in the form of nanobridges. Resistance values extracted from the current-voltage measurements for a large number of nanobridges with varying lengths and diameters are used to propose a model which highlights the relative contribution of the contact resistance to the total resistance for nanowire-based devices. It is shown that the contact resistance depends on the effective conducting cross-section area and hence is influenced by the presence of a surface depletion layer.
