We report the successful growth of thin GaN layers on (111) orientated Si substrates utilizing a newly developed pulse source injection molecular beam epitaxial (PSIMBE) technique.
Each cycle of deposition was comprised of 10 s of pre-purging, 3 s of TTIP source injection, and 1 s of H2O flow.
In addition, in modern power systems, the AC system fault characteristics can be severely impacted by adjacent HVDC links or renewable energy source injection together with its complex control systems.
In this work, an anti-snapback circuit technique called source injection (SI) is presented for the first time ever, which is shown to inhibit parasitic bipolar conduction during EOS/ESD events.
The gamma camera system was designed for monitoring the medical fields such as a radiopharmaceutical preparation lab or a patient waiting room (after source injection) in the division of nuclear medicine.
Schottky barrier field effect transistors (SB FETs) with Schottky source injection barrier contacts are fabricated using zinc oxide (ZnO) thin films deposited by pulsed laser deposition at room temperature.
Before the high-k HfO2 films deposition, 10 cycles SiO2 film was deposited at 250 °C by PEALD as interlayer, where one cycle consisted of 1 s Si source injection, 10 s N2 purging, 13.5 s oxidant injection, and 4 s N2 purging.
Subsequently, 5 nm HfO2/10 nm TiO2/5 nm HfO2 stacking structures were deposited in turn on Pt- and TiN-coated Si substrates at 250 °C by thermal ALD using Hf[N(C2H5 CH3]4 (TEMAH), TiCl4, and H2O as the Hf, Ti, and O precursors, respectively, where one oxide cycle consisted of 0.1s metal source injection, 4s N2 purging, 0.1s H2O injection, and 4s N2 purging.
Subsequently, 6 nm Al2O3/10 nm HfO2/3 nm Al2O3 stacking structures (Figure 1a) were deposited in turn on TiN-coated Si substrates at 250°C by thermal ALD using Hf[N(C2H5 CH3]4 (TEMAH), Al(CH3 3, and H2O as the Hf, Al, and O sources, respectively, where one oxide cycle consisted of 0.1-s metal source injection, 4-s N2 purging, 0.1-s H2O injection, and 4-s N2 purging.
In 2D space, assuming diffusivity anisotropy ( D x, D z ) a flow velocity (v x , v z ) and a point-source injection, Eq. (30) can be generalized as S ˙ n = ( D x ∂ x x + D z ∂ z z ) S n - f n ′ ( v x ∂ x + v z ∂ z ) S n + s 0 δ ( t ) δ ( x ) δ ( z ), (33 where s0 is the rate of injection per unit area and the solution to this equation yields the Green function.
