Using a previously shown method, we prepared 2”-GaN wafers as templates for a self separation process. Self separation is happening during cooldown after growing thick layers of GaN in our hydride vapor phase epitaxy (HVPE) reactor. Our templates consist of GaN grown by metalorganic vapor phase epitaxy (MOVPE) directly on sapphire. These GaN layers are masked with 200nm of SiN that are structur...
Metalorganic chemical vapor deposition (MOCVD) was used to deposit epitaxial BaTiO 3 thin films on (100) MgO substrates at 600'C. The metalorganic precursors employed in the deposition experiments were hydrated Ba(thd)2 (thd = CIIH190 2) and titanium isopropoxide. The films were analyzed by means of transmittance spectroscopy, wavelength dispersive x-ray spectrometry, secondary ion mass spectro...

We report on the metalorganic vapor phase epitaxial (MOVPE) growth of AlN films on sapphire substrates. The effect of precursor flow rate and nucleation layer (NL) on the film quality was investigated. The films were characterized using AFM, XRD and PL. We could realize AlN films with very smooth surfaces and narrow symmetric XRD peaks indicating low screw/mixed type dislocation densities in th...
