We developed and investigated the vertical diamond Schottky barrier diodes on large area IIb HPHT high quality substrates. The drift CVD layers with boron content of 10 16 2 × 17 cm −3 were made. possess an integral forward current higher than A in temperature range 25–200 °C. self‐heating effect further improves diode characteristics. tested different crystal‐to‐case thermal interfaces. Diodes have less 3.5 V voltage drop for at 25 °C 1 200 on‐resistance as low 0.05 Ω (10 mΩ ). calculated...
First, the Al/AlN/Al/Cr/diamond single crystal piezoelectric layered structure has been developed, and its properties have investigated up to 8 GHz. The peculiarities associated with influence of film on Q factor high overtones substrate pointed out. High ∼ 104 found at 6–7 GHz band.
Thin film material of oriented multiwall carbon nanotubes was obtained by noncatalytical chemical vapor deposition in a glow-discharge plasma. The phase composition, surface morphology, and structural features were studied Raman electron microscopy techniques. Low-voltage field emission thin nanotube examined diode configuration. I–V curves Fowler–Nordheim coordinates linear the corresponding threshold average about 1.5 V/μm. current density up to 50 mA/cm2 at 5 site reached 107 cm−2 same...
An investigation of the growth mechanisms, electronical and structural properties, field emissions carbon films obtained by chemical vapour deposition showed that from composed spatially oriented nanotubes plate-like graphite nanocrystals exhibit non-metallic behaviour. The experimental evidence work function local reduction for film materials is reported here. A model emission site proposed mechanism nanostructured described. In agreement with here, electron in different results sp3-like...
Thin film cold cathodes composed of a graphite-type carbon coating on Si substrate have been fabricated and tested. Electrons from the were emitted into vacuum when average electric field exceeded 1.5 V/μm. The emission current density was more than 1 mA/cm2 site higher 107 cm2 at 4 current–voltage dependencies studied different temperatures 77 to 600 K found be typical for emission. We propose mechanism electron cathodes, based enhancement due surface morphology modification electronic...
Abstract A novel method for preparing dilutely hydrogenated fullerenes H:C 60 is presented. DFT calculations of the Raman spectra at B3LYP/3‐21G level are compared with experimental data. Under laser treatment these phases form a rich variety dimeric and polymeric structures, quite in contrast to pristine C which forms dimers polymers bonded through [2 + 2] addition, heavily do not polymerize all. Dilutely differently, forming both double structures single dimers. We have shown that dilute...
