新主流电影中意识形态话语表述策略——以电影《我和我的……》系列为例

新主流电影是树立文化自信、建立民族文化和精神共同体的重要媒介。新主流电影凭借生动的故事和丰富的视听语言,实现主流意识形态和价值观念的传达。考察新主流电影意识形态话语表达的现代转型,关注主创人员如何将显性与隐性宣传教育有机整合,具有非常重要的现实意义。近些年来,新主流电影顺应时代发展,积极调整了意识形态表述策略,电影《我和我的……》系列就是其中的代表,在三年时间里以“国庆档献礼片”和“命题作文”的形式赢得了票房和口碑双丰收,其成功为我们提供了一个可资借鉴的样板。

Influence of the finite size effect of Si（001）/SiO2 interface on the gate leakage current in nano-scale transistors

With the device size gradually approaching the physical limit, the small changes of the Si(001)/SiO 2 interface in silicon-based devices may have a great impact on the device characteristics. Based on this, the bridge-oxygen model is used to construct the interface of different sizes, and the finite size effect of the interface between fine electronic structure silicon and silicon dioxide is studied. Then, the influence of the finite size effect on the electrical properties of nanotransistors is calculated by using the first principle. Theoretical calculation results demonstrate that the bond length of Si-Si and Si-O shows a saturate tendency when the size increases, while the absorption capacity of visible light and the barrier of the interface increase with the decrease of size. Finally, the results of two tunneling current models show that the finite size effect of Si(001)/SiO 2 interface can lead to a larger change in the gate leakage current of nano-scale devices, and the transition region and image potential, which play an important role in the calculation of interface characteristics of large-scale devices, show different sensitivities to the finite size effect. Therefore, the finite size effect of the interface on the gate leakage current cannot be ignored in nano-scale devices.
