The realization of the potential hybrid inorganic organic systems requires an understanding coupling between constituents: its nature and strength. observation optical transitions in monolayer WS 2 /terrylene is reported. first‐principle calculations, linear optical, transient absorption spectroscopy are employed to investigate spectrum hybrid, which exhibits a new transition that does not appear constituents’ spectra. calculations indicate type II level alignment, with highest occupied...
Scattering-type scanning near-field optical microscopy enables the measurement of constants a surface beyond diffraction limit. Its compatibility with pulsed sources is hampered by requirement high-repetition rate imposed lock-in detection. We describe sampling method, called quadrature-assisted discrete (quad) demodulation, which circumvents this constraint. Quad demodulation operates measuring signal and modulation phases for each individual light pulse. This method retrieves in...
We present quadrature-assisted discrete demodulation, which circumvents constraints imposed on the repetition rate by lock-in detection. The method enables pseudo-heterodyne near-field microscopy with kHz fs laser systems.
