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 ...

accompanied by a broad two-photon luminescence (TPL) peak with comparable intensity. The TPL peak occurs at the anti-bonding dipolar resonance wavelength∼550nm(Fig.1e), which provides a doubly-resonant enhancement mechanism for the TPL

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...
In Fig. 2(c), at the corresponding reflection peak (III), it is clear to shown that the propagated 1st SPP over the Al mirror is excited in the UV range. This demonstrates that, the higher-order MP resonant modes of 3D-AlSRR can couple with the propagated SPPs above the surface of ...

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 ...
