Our measurements also show that both the second- to first-order Raman peak intensity ratio [I(2TA)int./I(1TO)int. and I(2TO)int./I(1TO)int.] and the Raman relative intensities [I(2TA)int./I(2TO)int.] increase with increasing temperature. TEM image of SiNWs. The SiNW are 15...
hexagonal GaN,ZnO, and AlN.The cutoff frequency at 1926cm -1 of the second-order Raman is not the overtone of the A 1(LO) peak of the n-type doping 4H-SiC,but that of the undoping one.The second-order Raman spectrum of 4H-SiC can hardly be affected by doping species or doping ...

The structure, equation of state, IR, Raman, and inelastic neutron scattering (INS) spectra of high-pressure, proton-ordered phase VIII of ice are calculated by the second-order many-body perturbation and coupled-cluster singles and doubles methods. Nearly all the observed features of the pressur...

The temperature dependence of torsional strain is expressed in the form of a characteristic curve, the peak value falling at 100 C and the high rate increase occurring in the range 20-100 C.Z. Koran... Z Koran - 《Wood & Fiber Science》 被引量: 0发表: 2007年 加载更多来源...
Maria A Vincenti4, Domenico de Ceglia4, Costantino de Angelis5, Yuerui Lu6 and Dragomir N Neshev1 Two-dimensional transition-metal dichalcogenides (TMDCs) with intrinsically broken crystal inversion symmetry and large second- order nonlinear responses have shown great promise for future nonlinear light...
We posit that while Ge-Te bonds are consolidated closer to the phase transition to stabilize the cubic structure, the second-nearest neighbors of Ge-Ge and Te-Te are not as settled, only reaching peak strength with further temperature increases. It should also be noted that in experimental ...
of 300 ps covering the coincidence peak, while the accidental coincidence count is estimated by the average of counts within three 300-ps time windows away from the coincidence peak (see Supplementary Fig.1b). The CAR reaches a maximum value of 52,600 when the pump power is 0.27 mW...
