barrier width meaning in English
势垒宽度
Examples
- And emission wavelength depends on ratio of well / barrier width more than number of wells . some useful data has been found through experiments
阱垒宽厚度比a较之mqw的周期数目n对pl发光波长的影响更大。 - ( 2 ) several samples of different structure parameters are grown by low - pressure metal - organic chemical vapor deposition ( lp - mocvd ) . it is found that pl peak intensity , full width at half maximum ( fwhm ) and light output intensity are greatly dependent on number of wells . ratio of well / barrier width nearly has no effect on pl peak intensity and fwhm , but has little relation to light output intensity
通过分析pls ，可以及时获取材料生长和结构设计的数据，对质量控制有重要的指导意义； ( 2 )对不同结构的gainp algainp多量子阱样品进行了光致发光及出光强度的测量，发现mqw的周期数目n对pl峰强度、半峰宽和出光强度的影响最大；阱垒宽厚度比a对pl峰强度和半峰宽的影响较小，但对发光强度的影响较大。 - For the first current plateau ， two kinds of sequential resonant tunneling of - process and - x process are observed in the wide barrier gaas / alas superlattice under various pressures for p < 2kbar ， the high field domain is formed by - process ， while for p > 2kbar ， the high field domain is formed by - x process when the barrier width was decreased to 2nm , we found that ground - state -
对于宽垒( > 3 . 5nm )的gaaa / alas超晶格，当流体静压力超过临界压力2kbar后，平台宽度随压力的升高而收缩。对于窄垒( 2nm ) gaaa / alas超晶格， u - i曲线上的平台将不随压力变窄。
