Abstract: DOI: 10.1002/adom.201901084 The generation of short-wavelength polaritons from long-wavelength photons of the same energy can be inefficient due to their momentum mismatch. Hence, to launch polaritons from far-field illumination, phase matching is required.[3] One way… read more here.

Abstract: Peak force infrared (PFIR) microscopy is an emerging atomic force microscopy (AFM)-based infrared microscopy that bypasses Abbe's diffraction limit on spatial resolution. The PFIR microscopy utilizes a nanoscopically sharp AFM tip to mechanically detect the… read more here.
