The effect of thin film morphology, carbon monoxide (CO) and resistor geometry on the response of hydrogen sensitive thin film palladium resistors has been investigated. Films with two different morphologies were fabricated by DC magnetron sputtering

Nanocrystalline-TiN/amorphous-SixNy films were reactively co-sputtered from pure Ti and Si targets over the mid-frequency range of 50–250 kHz using two asymmetric bipolar pulsed direct current power supplies. The pulsing frequency was varied in thi

By controlling the pretreatment processes and deposition parameters on silicon substrates, diamond thin films with different surface roughness and sp 2 /sp 3 ratio were used as an interlayer for subsequent c-BN (cubic boron nitride) thin film deposit

Diamond and B4C coatings were used as an interlayer for the growth of cubic boron nitride thin films on c-silicon. By employing a B-C-N gradient layer on top of the B4C interlayer, improved adhesion occured between BN and B4C. A multi-step process af

Cubic boron nitride thin films were prepared by sputtering a hexagonal BN target with an unbalanced magnetron using pulsed d.c. biasing of the crystalline silicon substrate. An additional balanced magnetron was used to co-sputter aluminum in order to

The Mueller matrices describing oblique incidence reflection and normal incidence transmission have been measured for sculptured thin films (STFs) by glancing angle deposition with simultaneous substrate rotation. In data reduction, the 15 parameters

It is shown that the Bragg centre-wavelength of a polymeric chiral sculptured thin film (STF) can be shifted by the axial tension generated in a cobonded piezoelectric disc by a DC voltage. This attractive possibility can be exploited for tunable opt

Polymeric chiral sculptured thin films (STFs) can act as lasers in the so-called Bragg regime, if doped with appropriate dyes. We propose a piezoelectric control mechanism to tune such lasers. The negative piezoelectric effect in a piezoelectric laye

Boron nitride (BN) films with high cubic content were deposited using pulsed dc sputtering of a B4C target and rf biasing of the substrate. The film deposition was characterized using ultraviolet-extended real-time spectroscopic ellipsometry (UV-RTSE
