Gold nanocluster thin films (∼ 200 nm thickness) consisting of metal clusters ∼ 5 nm in size embedded in a matrix of Nb2O5 were deposited by ion beam-assisted deposition (IBAD) by coevaporation of Au and Nb with O2+ ion bombardment. The microstru

Pulsed laser deposition (PLD) of thin films involves conditions that differ substantially from those of other vapor deposition techniques and that may be expected to influence film nucleation and growth mechanisms. In order to study the effect of the

Thin (0.3–50 μm) films of SrxBa(1−x)TiO3 (SBT) with x=0.35 − 0.8 have been deposited by pulsed laser deposition onto single crystals of MgO, LaAlO3 and thin films of YBa2Cu3O7−δ. The SBT films were characterized morphologically, structurall

The magnetic and structural properties of pulsed laser deposited MnZn–ferrite films have been examined. The results show that the uniaxial anisotropy, ferromagnetic resonance linewidth and coercive force are strongly influenced by the microstructur

Superlattices composed of III–V heterostructures have established applications in high‐speed electronic and optoelectronic devices. As layer thicknesses are reduced, the role of heterostructure interface sharpness becomes more critical to ensurin
