Název v původním jazyce

Constant amplitude driving of a radio frequency excited plasmonic tunnel junction

Popis výsledku v původním jazyce

Constant amplitude bias modulation over a broad range of microwave frequencies is a prerequisite for application in high-resolution spectroscopic techniques in a tunnel junction, e.g., electron spin resonance spectroscopy or optically detected paramagnetic resonance. Here, we present an optical method for determining the frequency-dependent magnitude of the transfer function of a dedicated high-frequency line integrated with a scanning probe microscope. The method relies on determining the energy cutoff of the plasmonic electroluminescence spectrum, which is linked to the energies of the electrons inelastically tunneling across the junction. We develop an easy-to-implement procedure for effective compensation of an radio frequency line and determination of the transfer function magnitude in the GHz range. We compare our method with conventional fully electronic calibration and find a perfect agreement.
