چکیده
We describe the magnetic domain structures and magnetoelectric coupling in self-assembled BiFeO3–CoFe2O4 (BFO–CFO) nanocomposite thin films grown on (110)-LaAlO3 substrates, consisting of CFO slab-shaped crystals (nanofins) embedded a BFO matrix. The nanofins exhibit single-domain states with in-plane magnetization along their length due to shape magnetoelastic anisotropies. piezoresponse matrix is affected by applying an hard axis field, indicating within multiferroic composite. Conversely, applied electric field leads reversal fraction as strain transferred from alters anisotropy, enabling switching driven magnetostatic interactions.

We propose a self-assembling procedure for the fabrication of GaAs islands by Droplet Epitaxy on silicon substrate. Controlling substrate temperature and amount of supplied gallium is possible to tune the base size of the islands from 70 up to 250 nm and the density from 10(7) to 10(9) cm(-2). The islands show a standard deviation of base size distribution below 10% and their shape evolves chan...

The size distribution of self-assembled InAs quantum dots grown on (001) InP under the StranskiKrastanow growth mode is controlled using selective area/chemical beam epitaxy, which allows the formation of quantum dots at specific locations. As the dimensions of the patterned areas are decreased from 1000 nm down to 50 nm or less, scanning electron microscopy reveals a gradual increase in the sp...

The formation and structure of alkyltrichlorosilanes on several types of SrTiOs substrates have been studied. The silanes adsorb spontaneously from a hexadecane solution and form monolayers on all the substrates used. Characterization has been performed by atomic force microscopy, wettability, angle resolved X-ray photoelectron spectroscopy, reflection absorption infrared spectroscopy, and spec...
