The relationship between structural and electronic phase transitions in V2O3 thin films is of critical importance for understanding of the mechanism behind metal insulator transition (MIT) and related technological applications.Despite being extensively studied,there are currently no clear consensus and picture of the relation between structural and electronic phase transitions so far.Using V2O3 thin films grown on r-plane Al2O3 substrates,which exhibit abrupt MIT and structural phase transition,we show that the electronic phase transition occurs concurrently with the structural phase transition as revealed by the electrical transport and Raman spectra measurements.Our result provides experimental evidence for clarifying this issue,which could form the basis of theoretical studies as well as technological applications in V2O3.

摘 要:传统文化本身就是现代语文的建设基础,所以,在进行现代语文教学的过程中,传统文化的理解和深入探究,都能提升现代语文的教学效果,尤其是一些传统文化的内容,实质上和人们的生活是息息相关的, 从小到大的过程中,学生都听到过这些传统文化的内容,因此,在实际的教育教学中,也就可以保证相应教学效果的提升。同时,我国当前的语文课程教学也在积极改革,传统文化的融入就是一个核心的建设内容,而我国传统文化大都和
