Observation of conduction electron spin resonance in boron doped diamond
Péter Szirmai, Gábor Fábián, János Koltai +7
We observe the electron spin resonance of conduction electrons in boron doped (6400 ppm) superconducting diamond (Tc =3.8 K). We clearly identify the benchmarks of conduction elect…
Synthesis of Homogeneous Manganese-Doped Titanium Oxide Nanotubes from Titanate Precursors
Péter Szirmai, Endre Horváth, Bálint Náfrádi +6
We report a novel synthesis route of homogeneously manganese-doped titanium dioxide nanotubes in a broad concentration range. The scroll-type trititanate (H(2)Ti(3)O(7)) nanotubes…
A detailed analysis of the Raman spectra in superconducting boron doped nanocrystalline diamond
Péter Szirmai, Thomas Pichler, Oliver A. Williams +3
The light scattering properties of superconducting (Tc=3.8 K) heavily boron doped nanocrystalline diamond has been investigated by Raman spectroscopy using visible excitations. Fan…
Density of states deduced from ESR measurements on low-dimensional nanostructures; benchmarks to identify the ESR signals of graphene and SWCNTs
Péter Szirmai, Gábor Fábián, Balázs Dóra +6
Electron spin resonance (ESR) spectroscopy is an important tool to characterize the ground state of conduction electrons and to measure their spin-relaxation times. Observing ESR o…
