Latest Patents

Wang's latest patents include a groundbreaking system and method for a non-tapping mode scattering-type scanning near-field optical microscopy. This invention, known as peak-force scattering scanning near-field optical microscopy (PF-SNOM), addresses the limitations of conventional scattering-type microscopy techniques. Traditional methods often rely on tapping mode operation and lock-in detections, which do not provide direct tomographic information with explicit tip-sample distance. The PF-SNOM technique combines peak force tapping mode with time-gated light detection, enabling direct sectioning of vertical near-field signals from a sample surface. This advancement allows for both three-dimensional near-field imaging and spectroscopic analysis. Notably, PF-SNOM achieves a remarkable spatial resolution of 5 nm and can simultaneously measure mechanical and electrical properties alongside optical near-field signals.
