From then on , the above two shortcomings had been overcome . impurity concentration and junction depth can be accurately controlled and freely adjusted . both low and high dopant concentration can be gained easily , and ideal distribution of ga in si can also be achieved with uniform surface concentration , good repeatability and high eligibility and excellence ratio , which have greatly improved comprehensive performances of the devices 此工艺发明以来,克服了上述两者的弊端,杂质浓度和结深能准确控制而又能任意调整,可进行低、高浓度阶段性掺杂,得到元素ga在si中的理想分布,而且表面浓度均匀一致、重复性好、合格率和优品率高,改善和提高了器件的综合性能。
A method to calculate quantitatively the adsorption volume or adsorption space of per mass of adsorbent derived from both the adsorbed molecule volume and the maximum adsorbance of a solute in an adsorption isotherm under a given experimential condition is presented firstly for a solid / liquid adsorption system of the solute in a dilute aqueous solution . this method is suitable for not only mono - layer adsorption , but also mani - layer adsorption and micelle adsorpion of surfactant constructed by hydrophile and lipophile groups . therefore , the surface concentration of the adsorbate , cs , deduced from the adsorption volume is possessed of the meaning of true concentration , and the value of the patition coefficient of the adsorbate between solid and liquid phass , p , attained by the cs and the c , solution concentration of the adsorbate , can be accurate . the foregoing a set of calculations are presented for the solid - liquid adsorption systems consisted of the wool fiber and separately dodecyltrimethyl - ammonium bromide ( dtab ) and hexadecyltrimethyl - ammonium bromide ( ctab ) in this paper . this provides a strong basis for adsorption thermodynamic investigation of adsorbate 对稀溶液中溶质的固/液吸附体系,首次提出了根据吸附分子体积和实验条件下吸附等温线中的最大吸附量计算单位质量吸附剂的吸附体积或吸附空间的方法.此法适用于单层吸附,也适用于多层吸附和具有亲水亲油结构的表面活性剂分子的胶团吸附.由此,吸附质的表面相浓度cs具有真实浓度的含义,相应地,计算得到的溶质的固/液分配系数p就有了准确值.分别计算由溴代十二烷基三甲铵( dtab )和溴代十六烷基三甲铵( ctab )与羊毛纤维构成的液/固体系分配系数等,为溶质吸附的热力学研究奠定了基础
