Effect of H on Si molecular‐beam epitaxy

Effect of H on Si molecular-beam epitaxy

In Si crystal growth by molecular-beam epitaxy (MBE) at low temperatures there is known to be an epitaxial thickness: an initially crystalline regime before the deposited film becomes amorphous. The predominant impurity in MBE is hydrogen, but the role of background H in low-temperature MBE has not previously been assessed. Here the effect of deliberate dosing of the Si surface with atomic H du...

effect of oral presentation on development of l2 learners grammar

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...

Molecular - beam epitaxy of CrSi 2 on Si ( 111 )

Chromium disilicide layers have been grown on Si ( 111) in a commercial molecular-beam epitaxy machine. Thin layers ( l 0 nm) exhibit two epitaxial relationships, which have been identified as CrSi2 (0001)//Si(lll) with CrSi2 [10lO]//Si[10l], and CrSi2 (0001)//Si(lll) with CrSi2 [ 1120 ]I /Si [ 101]. The latter case represents a 30° rotation of the CrSi2 layer about the Si surface normal relati...
