Superconductivity in oxygen doped iron telluride by molecular beam epitaxy
… by can become one when doped with oxygen. In this investigation, we developed the growth recipe of thin film iron telluride by Molecular Beam Epitaxy (MBE). We found the growth to be self-regulated, similar to that of GaAs. The initial layers of growth seem to experience a …

Growth and characterisation of thin films of CuCl and related materials
… they have on the resultant thin films. P-type doping has also been performed with oxygen. Characterisation of these doped and undoped γ-CuCl samples has been performed. Reflectance and X-ray diffraction measurements show the effect the oxygen doping has on the structural and optical properties …

Optical dielectric properties of YBa2Cu3O6+x and Ba1-xKxBiO
… systems are studied as a function of doping. For the YBa2Cu3O6+x system, a sharp peak in the imaginary part of the dielectric function near 4.0eV is examined as a function of oxygen doping. The anisotropy present in this system for higher levels of doping is observed to induce a …

Growth kinetics and doping of gallium nitride grown by rf-plasma assisted molecular beam epitaxy
… approaching a monolayer for heavier doping levels. Transmission electron microscopy studies indicate the surface layer of Be has a significant effect on structure, with severe degradation occurring when accumulation nears monolayer coverage.;High-quality GaN films were grown to study …

Spin and Charge Dynamics in Organic Semiconductors
… transport characteristics together with their oxygen doping beha viour. We see that d-d derivatives behave significantly different to their d-a counterparts and can be grouped by certain sub-features within the d-d category. We see evidence that this is due to a lack of order in d-d derivatives …

Probing nano-scale atomic and electronic structures of iron-based superconductors
… and emergence of superconductivity by isovalent doping. The iron-based high-Tc superconductors belong to the structure families of chalcogenides and pnictides. Crystal structures and bonding have large effects on superconductivity in these materials. Investigating atomic and electronic structures …
