提出采用紫外光刻工艺制作传统波导结构之后,通过电子束曝光和干法刻蚀制作光子晶体小孔的工艺方案,大幅度减低了制作成本;设计出可形成空气桥结构、并且适用于电子束曝光位置识别的光刻模板,在SOI材料上成功制作出带有空气桥刻蚀预留槽以及接续光波导的结构,在该结构上成功实现了光子晶体带隙波导的电子束曝光,带隙波导与接续光波导位置接续良好;最后利用预留槽进行了刻蚀牺牲层的实验,为下一步利用光子晶体小孔刻蚀牺牲层形成空气桥结构打下了基础。 |

摘要针对当前日益严重的腐败现象,从经济学“成本-收益”角度分析腐败产生的经济学根源,然后通过建立腐败者的“成本-收益”数学模型并进行分析,提出从加大腐败成本角度着手抑制腐败,最根本的是通过对资源配置的“非人格化”,减少权力资本化的机会。 |
