Deconvolution of the density of states of tip and sample through constant-current tunneling spectroscopy
We introduce a scheme to obtain the deconvolved density of states (DOS) of the tip and sample, from scanning tunneling spectra determined in the constant-current mode (z-V spectroscopy). The scheme is based on the validity of the Wentzel-Kramers-Brillouin (WKB) approximation and the trapezoidal approximation of the electron potential within the tunneling barrier. In a numerical treatment of z-V...
متن کاملProbing the 4f states of ceria by tunneling spectroscopy.
Low-temperature scanning tunneling microscopy and spectroscopy have been employed to analyze the local electronic structure of the (111) surface of a ceria thin film grown on Ru(0001). On pristine, defect-free oxide terraces, the empty 4f states of Ce(4+) ions appear as the only spectral feature inside the 6 eV oxide band gap. In contrast, occupied states are detected between -1.0 and -1.5 eV b...
متن کاملComparative study of atomic force mode and tunneling mode tip-enhanced Raman spectroscopy
In Tip-Enhanced Raman Spectroscopy (TERS) a metal (or metallized) sharp tip is used to enhance the electromagnetic field by a localized surface-plasmon excitation. Two different modes – atomic force mode (AFM) and scanning tunneling mode (STM) – together with their respective types of probe tips are used in TERS experiments. We have compared the efficiency in enhancing the Raman signal on a thi...
متن کاملTip-enhanced optical spectroscopy.
Spectroscopic methods with high spatial resolution are essential for understanding the physical and chemical properties of nanoscale materials including biological proteins, quantum structures and nanocomposite materials. In this paper, we describe microscopic techniques which rely on the enhanced electric field near a sharp, laser-irradiated metal tip. This confined light-source can be used fo...
متن کاملTunneling Spectroscopy of PCCO
A point-contact probe capable of operating down to temperatures of 1.5 K and in magnetic fields of up to 32 T was designed and constructed. With this probe, preliminary data was obtained on Pr2-xCexCuO4 (PCCO) which reproduced previously published data in fields up to 8 T and temperatures down to 4.2 K. What is a superconductor? A material that can carry current without resistance at temperatur...
