DNA detection by THz pumping

Our results demonstrate a new method for label-free, real-time oligonucleotide characterisation by their self-resonant modes, which are unique to their conformation and sequence. We anticipate that our assay will be used as a starting point for a more detailed investigation of the aforementioned mechanism, which can be used as a basis for oligonucleotide detection and analysis. Furthermore, this technique can be applied to improve existing modern genetics technologies.

Magnetic resonance spectroscopy of single centers in silicon quantum wells

We present the new optically-detected magnetic resonance (ODMR) technique which reveals single point defects in silicon quantum wells embedded in microcavities within frameworks of the excitonic normal-mode coupling (NMC) without the external cavity and the hf source.

Silicon nanostructures embedded in superconductor shells

We present the findings of the superconductivity in the silicon nanostructures prepared by short time diffusion of boron of the n - type Si (100) surface. These Si - based nanostructures represent the p - type ultra-narrow self - assembled silicon quantum wells confined by the delta - barriers heavily with boron. The resistivity, thermo - emf and magnetic susceptibility studies show that the high temperature superconductivity observed seems to result from the single - hole tunnelling into the negative - U boron centres at the silicon quantum well - delta - barier interfaces.
