This paper deals with theory of large radius polaron effect in quantum wells, wires and dots. The interaction of charge particles and excitons with both bulk and interface optical phonons is taken into consideration. The analytical expression for polaron binding energy is obtained for different types of nanostructures. It is shown that the contribution of interface phonons to the polaron binding energy...
It was demonstrated that the etching in HF-based aqueous solution containing AgNO 3 and Na 2 S 2 O 8 as oxidizing agents or by Au-assisted electroless etching in HF/H 2 O 2 solution at 50°C yields films composed of aligned Si nanowire (SiNW). SiNW of diameters ∼10nm were formed. The morphology and the photoluminescence (PL) of the etched layer as a function...
