We studied the effect of magnetic doping with Gd atoms on the superconducting properties of amorphous Mo70Ge30 films. We observed that in uniform films deposited on amorphous Ge, the pair-breaking strength per impurity strongly decreases with film thickness initially and saturates at a finite value in films with thickness below the spin-orbit scattering length. The variation is likely caused by surface-induced magnetic anisotropy and is consistent with the fermionic mechanism of superconductivity suppression. In thin films deposited on SiN the pair-breaking strength becomes zero. Possible reasons for this anomalous response are discussed. The morphological distinctions between the films of the two types were identified using atomic force microscopy with a carbon nanotube tip.

“…The 2D (x-z) fluorescence image in Fig. 1(b) demonstrates that CNTs attached to AFM probes can be used for nanometer-scale energy transfer microscopy [13]; QD-functionalized probes have been used in a similar manner previously [14]. 1D approach curves can also be extracted from the same 3D data set [12], or by halting the lateral scan when the CNT is centered above the QD (Fig.…”

Energy Transfer from an Individual Quantum Dot to a Carbon Nanotube

Precision measurements of resonant energy transfer from isolated quantum dots (QDs) to individual carbon nanotubes (CNTs) exhibit unique features due to the one-dimensional nature of CNTs. In particular, excitons can be created at varying distances from the QD at different locations along the CNT length. This leads to large variations in energy transfer length scales for different QDs and a novel saturation of the energy transfer efficiency at ∼96%, seemingly independent of CNT chirality.

“…We focus here on the combination of the antenna and near-field effects, and their influence on the process of the spontaneous decay of an emitter coupled to a SWNT nanoantenna. Besides a fundamental theoretical interest, practical applications can be foreseen, for example, in the fluorescence microscopy with SWNT-based probes [34,35]. Moreover, the integration of SWNTs as nanoantennas with the nanoscale luminescent materials such as quantum dots [36][37][38] allows multifunctional nanostructures.…”

Spontaneous decay of the excited state of an emitter near a finite-length metallic carbon nanotube

et al. 2010

The spontaneous decay of an excited state of an emitter placed in the vicinity of a metallic single-wall carbon nanotube (SWNT) was examined theoretically. The emitter-SWNT coupling strongly depends on the position of the emitter relative to the SWNT, the length of the SWNT, the dipole transition frequency and the orientation of the emitter. In the high-frequency regime, dips in the spectrum of the spontaneous decay rate exist at the resonance frequencies in the spectrum of the SWNT conductivity. In the intermediate-frequency regime, the SWNT conductivity is very low, and the spontaneous decay rate is practically unaffected by the SWNT. In the low-frequency regime, the spectrum of the spontaneous decay rate contains resonances at the antennas resonance frequencies for surface-wave propagation in the SWNT. Enhancement of both the total and radiative spontaneous decay rates by several orders in magnitude is predicted at these resonance frequencies. The strong emitter-field coupling is achieved, in spite of the low Q factor of the antenna resonances, due to the very high magnitude of the electromagnetic field in the near-field zone. The vacuum Rabi oscillations of the population of the excited emitter state are exhibited when the emitter is coupled to an antenna resonance of the SWNT.
