When a pump beam (He-Cd laser) irradiated the QDs, the quantum yields of the photoluminescence emissions from the QDs were increased by a post-treatment effect caused by the
As the substrate temperature was increased, the crystallinity was found to be improved, and the transmittance of the ITO film grown at 250 ◦ C was higher by 24 % compared to that of

The signal intensity of the Ti 3+ center hardly depends on the [Li]/[Nb] ratio while that of the Nb 4+ in the K 2 O doped crystal is found to be lower than that in the other,
Through the multiple reconstructions observed by using RHEED patterns, we were able to confirm the appropriate quantity of C-atoms in the c(4 × 4) reconstruction. Also, by using
The flame tube experiment has the advantages of making a standing wave, measuring the speed of sound, and analyzing the longitudinal wave as a transverse wave. We find the
Resonant and non-resonant Raman scatter- ing spectra from 3 ML-thick CdSe/ZnSe self-assembled quantum dot structure excited at energies of 2.21 eV and 2.54 eV from top to
We have investigated the electrical characteristics of three different stacks of ohmic contacts (TiW/Ti/Pt, TiW, and Ni/TaSi x /Pt) on highly doped n-type 4H-silicon carbide for
