Parasitic amorphous on single-domain crystal: Structural observations of silicate glass-ceramics
Glass-ceramics (GCs) are materials obtained from the crystallisation of functional phases in glass, and have a structure that the crystallised phase embedded in the glass matrix. Glass-forming oxides are commonly added to the functional phases to improve the stability of precursor glass; however, the issue of glass-ceramics permitting the presence of residual phases resulting from addition is r...
متن کاملAmorphous Silicon Core-shell Nanowire Solar Cells
Nanostructures such as nanoparticles and nanowires have been demonstrated as powerful tools to improve light absorption[1-4], to enable low temperature process[5], to demonstrate multi-exciton generation[6], and to decouple the absorption depth and carrier diffusion length[7, 8]. Here we demonstrated the first amorphous silicon coreshell nanowire solar cells, which can be fabricated through a l...
متن کاملCloning of conserved regions of nontypeable Haemophilus influenzae hmw1 core binding domain
Colonization of nontypeable Haemophilus influenzae (NTHi) in nasopharynx causes respiratory tract disease. In 80% of clinical isolates, HMW proteins are the major adhesions and induce protective antibodies in the hosts. Therefore, it can be used as a vaccine candidate. The aim of this study is designing and cloning of the conserved regions of NTHi hmw1 core binding domain.In this study, the sta...
متن کاملDomain Wall Propagation in Bistable Amorphous Microwires
Tendency on miniaturization of the modern magnetic sensors and devices stimulates development of such magnetic materials with reduced dimensionality. Therefore magnetic materials with outstanding magnetic characteristics and reduced dimensionality recently gained much attention. Consequently thin wire with reduced geometrical dimensions (of order of 1-30 μm in diameter) gained importance within...
متن کاملOptical properties of crystalline-amorphous core-shell silicon nanowires.
The optical absorption in a nanowire heterostructure consisting of a crystalline silicon core surrounded by a conformal shell of amorphous silicon is studied. We show that they exhibit extremely high absorption of 95% at short wavelengths (λ < 550 nm) and a concomitant very low absorption of down to less than 2% at long wavelengths (λ > 780 nm). These results indicate that our nanowires do not ...
