Circular dichroism mapping (CDM) method was introduced by utilizing the highly collimated light beam of synchrotron radiation (SR) available at Diamond Light Source B23 beamline for scanning the thin films of the NTB phase. We apply SR-CDM to two ach... Read More about Mapping the local ambidextrous chirality in thin films of NTB phase by circular dichroism spectra.
