Summary on Grant Application Form
Photon emission scanning tunnelling microscopy (PETSM) has immense potential for the combined study of optical, electronic, structural and even magnetic properties at the nanometre or molecular scale. We aim to develop an ultra high vacuum (UHV) PETSM system dedicated to the investigation of a range of novel nanoscale and molecular systems. An important focus will be the determination of the effects of molecular structure, ordering conformation and molecule-substrate interactions on the intensity and spectrum of light emitted from individual organic molecules absorbed on semiconductor surfaces. Hybrid organic-inorganic heterosystems, where molecular nanostructures are integrated with conventional inorganic semiconductors, will play an increasingly important role in nanotechnology research and a novel system we will investigate is the combination of functionalised fullerenes and Si substrates. A challenging and exciting extension of the PETSM technique we wish to develop is the optical probing of nanoscale magnetic properties. We will use surface passivation techniques to produce high quality GaAs tips and exploit the dependence of the polarisation of recombination luminescence from these tips on the spin polarisation of the tunnelling electrons to develop magnetic imaging techniques. A number of unique investigations into the nanoscale magnetic properties of transition metal clusters are planned.
