According to the raman selection rule and the pl measurement, it is reasonable to evaluate the quality of galnp / algalnp mqw by analyzing the relative intensity ratio of a1p - lo / to. ( 4 ) a new modified random element isodisplacement ( mrei ) model is set up to calculate the dependence between the long - wavelength optical phonon frequencies and the composition of iii - v - type ab1 - xcx mixed crystals. the second neighbor force constants are still assumed to be a linear variation with the composition, but the two first neighbor force constants can be evaluated to be a negative exponent variation with the composition, using the overlapped repulsive potential of the ion crystal combination
通過實驗我們找到了在這些結構參數上生產gainp algainpmqw的較理想的結果; ( 3 )首次用喇曼( raman )散射方法研究了常溫下的gainp algainp多量子阱結構,除了指認出喇曼光譜中各光學聲子模外,還結合樣品光致發光譜的測量結果,分析發現喇曼光譜中alp - lo to的相對強度比可以在一定程度上評定晶體gainp algainpmqw的生長質量; ( 4 )在修正的隨機元素等位移? mrei模型的基礎上建立了一個新模型,計算了ab _ ( 1 - x ) c _ x型?族半導體混晶的長波長光學聲子模頻率的組分變化關系。The synthesis process of single - wall carbon nanotubes ( swnts ) by catalytically chemical vapor deposition ( ccvd ) was investigated and the product was characterized with transmission electron microscopy ( tem ), electron diffraction ( ed ), electron dispersive spectra ( eds ) and raman scattering spectra etc. pyrolysis of methane over solid catalysts prepared with impregnation, ion - adsorption precipitation, and sol - gel technique can all lead to the growth of swnts
本文研究了單壁納米碳管的化學氣相沉積法( cvd )制備工藝,並運用透射電子顯微鏡( tem ) 、 x - ray能譜( eds )與喇曼( raman )光譜等分析手段,對產物及催化劑進行了表徵。採用浸漬法、吸附沉澱法與溶膠凝膠法等制備了催化劑,併合成了單壁納米碳管。As is shown in this paper, when the length of liquid - core optical fiber full of liquid of carbon disulfide disulphide is four meters, the maximum raman spectrum can be received, compared it with optical spectrum measured by absorption cell, it is enhanced by more than one hundred times
採用此聯用技術,當液芯光纖芯內樣品為二硫化碳( cs _ 2 ) ,液芯光纖的長度為4米時獲得的喇曼光譜強度最大。此時的喇曼光譜強度比吸收池方法獲得的喇曼光譜強度提高兩個數量級以上。( 2 ) iiexagofla1 and cubic gan epitaxia1 1ayers were grown by meta1organic chemical vapoi " deposit ion ( m0cvd ). the x - - ray di ffract ion ( xrd ), photo - 1umi nescence ( i3l ), raman scatter i ng spectra ( raman ) were appl ied to s tudy the samp1es, and we made some detai 1ed discuss ion
( 2 )我們對用mocvd方法生長的六方相、立方相兩類gan樣品材料進行了x射線衍射( xrd ) ,光致發光譜( pl ) ,喇曼( raman )散射譜的測量,並對測量結果作了較為詳細的分析與討論。分享友人
