We build an experiment system based on total reflection (TR) method to observe the evolution of real contact area of polymethyl methacrylate (PMMA) in the conti
A 10-channel Hα diagnostic system has been designed with the rapid response rate of 300 kHz,spatial resolution of about 40 mm,and overlap between adjacent chan
The evolution of electron correlation and charge density wave (CDW) in 1T-TaS2 single crystal has been investi-gated by temperature-dependent Raman scattering,
