A pioneer in TERS
“The nano-Raman team of LPICM lab, Ecole Polytechnique, developed jointly with HORIBA Scientific the first HORIBA TERS system prototype a dozen or so years ago. Later commercialized, the prototype featured STM and AFM SPM modes combined with side illumination in Raman backscattering configuration. Owing to its excellent performance and relative ease of use, it was applied with success to the study of various materials and nanostructures such as self-assembled organic monolayers, carbon nanotubes, patterned semiconductors, etc. Among the outstanding scientific successes achieved with the system, the world premiere demonstration of stimulated (pump - probe) TERS is to be mentioned. Being quite user-open and versatile, the prototype measurement configuration could be successfully adapted to accommodate a polarization control of both excitation and scattered radiations, an external laser pump, as well as an additional detector for Tip-Enhanced Photoluminescence.
Since the pioneering years of the TERS prototype, HORIBA Scientific have developed a novel, module-based TERS system featuring a large number of SPM modes (STM, AFM, tuning-fork, etc.) implementable under various illumination – collection conditions (off-axis, top and bottom backscattering). Thanks to the customer-oriented culture of HORIBA, the nano-Raman team of LPICM is currently updating its “historical” prototype with the novel TERS system. It will allow us not only to pursue our actual research topics by adding new measurements, but also to initiate new research areas, impossible to address with the present system.”
