硼當量 的英文怎麼說
中文拼音 [péngdāngliáng]
硼當量
英文
boron equivalent-
Standard practice for determining equivalent boron contents of nuclear materials
核材料中當量硼含量測定的標準實施規范Anti - oxidation temperature of diamond with 500 ppm boron reached 1070 specific resistance of diamond with 2158 ppm boron was 1. 93 cm
含硼500ppm的金剛石抗氧化溫度提高到1070 。當含硼量為2158ppm時金剛石的電阻率為1 . 93 ? cm 。Thus it is considered that the technique of dz formation by means of rtp may not be suitable for heavily boron - doping cz silicon. since the higher concentration vacancy could decrease the stress inducing by oxygen precipitates, the size of the oxygen precipitation with higher density was smaller in the hb si samples in comparison with the samples without rtp pre - annealing. moreover, as for the technique to generate dz by rtp in lightly boron - doping samples, it was found that the behavior of oxygen precipitation and dz was determined by the annealed temperature, followed annealing and ambient of rtf as well
結果顯示，對于普通輕摻矽片能形成明顯的很寬的潔凈區的rtp預處理工藝，應用於重摻硼樣品時沒有潔凈區形成，所以rtp預處理獲得潔凈區的工藝不適用於重摻硼矽片，硼的大量摻雜對氧沉澱促進效果大於高濃度的空位對氧沉澱的洲排浙江大學碩士學位論文李春龍：直拉重摻硼硅單晶中氧沉澱的研究促進效果；大量空位的引入，有利於釋放氧沉澱生長過程的內應力，適當增加重摻硼樣品氧沉澱密度，減少其尺寸，並伴有層錯生成。If the nabh4 addition amount was more, a double peak absorbance signal was obtained and the peak high was redaced
當硼氫化鈉加入量較大時，所得的信號存在雙峰，而且其峰高降低了很多。In order to prepare high quality films, appropriate temperature and r. f. power should be selected, and moreover, the content of the hydrogen need be controlled
因此制備薄膜與襯底結合良好、較高質量的氮化硼薄膜，應在適當的沉積溫度（ 420 ）和射頻功率（ 160w ）下並適當控制反應氣體中氫氣的含量。分享友人
