Mestre José Veiga, 4715-310 Braga, Portugal and Departamento de Física Aplicada, Universidad de Alicante, San Vicente del Raspeig, 03690, Spain A scanning tunneling microscope can probe the inelastic spin excitations of single magnetic atoms in a surface via spinip assisted tunneling. A particular and i...

Atomic resolution imaging is demonstrated using a hybrid scanning tunneling/near-field microwave microscope. The microwave channels of the microscope correspond to the resonant frequency and quality factor of a coaxial microwave resonator, which is built in to the scan head. The microscope is capable of simultaneously recording the low frequency tunnel current !0–10 kHz" and the information fro...

The relationship between the electrocatalytic properties of an electrode and its ability to transfer electrons between the electrode and a metallic tip in a scanning tunneling microscope (STM) is investigated. The alkaline oxygen evolution reaction (OER) was used as a test reaction with four different metallic glasses, Ni78Si8B14, Ni70Mo20Si5B5, Ni58Co20Si10B12, and Ni25Co50Si15B10, as electrod...

Localized spectroscopy with simultaneous topographic, elemental and magnetic information is presented. A synchrotron X-ray scanning tunneling microscope has been employed for the local study of the X-ray magnetic circular dichroism at the Fe L2,3-edges of a thin iron film grown on Cu(111). Polarization-dependent X-ray absorption spectra have been obtained through a tunneling smart tip that serv...

nano films consisting of an alternating sequence of positively and negatively charged polyelectrolytes have been prepared by means of the electrostatic layer-by-layer (lbl) sequential assembly technique on treated and untreated mild steel wires. inhibitor was encapsulated between cationic and anionic polyelectrolyte nano films. this paper mainly focuses on the effect of these nano-films of poly...

Accurate calculation of the tunneling currents in a scanning microscope (STM) is needed for developing image processing algorithms that convert raw data STM into surface topographic images. In this paper, an accurate current several tip–sample distances, bias voltages, and tips hyperboloidal shape with radii curvature carried out. The main features are following. Non-WKB exact solutions to trap...
