Latest Patents

Chelly holds a patent for a photodetector designed for use in a scanning probe microscope. This detector device features an integral semiconductor structure that defines a cantilever and tip probe assembly. The assembly includes at least one tip, which is configured as an apertured photodetector. This photodetector comprises a layered structure with a subwavelength aperture that allows for the collection of evanescent waves created at a surface region. The interaction of these waves with the depletion region results in the direct conversion of the collected waves into electric signals, which can be read by the electrical circuit within the tip apex portion. This innovative design enables concurrent monitoring of both topographic and optical properties of the scanned surface.
