The phonon density of states of the ferroelectric (paraelectric) phase shows two (one) distinct band gaps separating the high-frequency (~800 cm−1) optical branches from the continuum of acoustic and lower optical phonon states. This result leads to specific heat capacites in close agreement with experimental measurements in the range 0–350 K and a Debye temperature of 574 K. The calculated zero-point renormalization of the electronic Kohn–Sham eigenvalues reveals a strong dependence on the phonon wave vectors, especially near Γ. Integrated over all phonon modes, our results indicate a vibrational correction of the electronic band gap of 0.41 eV at 0 K, which is in excellent agreement with the extrapolated temperature-dependent measurements.}}, author = {{Friedrich, Michael and Riefer, Arthur and Sanna, Simone and Schmidt, Wolf Gero and Schindlmayr, Arno}}, issn = {{1361-648X}}, journal = {{Journal of Physics: Condensed Matter}}, number = {{38}}, publisher = {{IOP Publishing}}, title = {{{Phonon dispersion and zero-point renormalization of LiNbO3 from density-functional perturbation theory}}}, doi = {{10.1088/0953-8984/27/38/385402}}, volume = {{27}}, year = {{2015}}, } @article{13493, author = {{Müllegger, Stefan and Rauls, Eva and Gerstmann, Uwe and Tebi, Stefano and Serrano, Giulia and Wiespointner-Baumgarthuber, Stefan and Schmidt, Wolf Gero and Koch, Reinhold}}, issn = {{1098-0121}}, journal = {{Physical Review B}}, number = {{22}}, title = {{{Mechanism for nuclear and electron spin excitation by radio frequency current}}}, doi = {{10.1103/physrevb.92.220418}}, volume = {{92}}, year = {{2015}}, } @article{13496, author = {{Edler, F. and Miccoli, I. and Demuth, S. and Pfnür, H. and Wippermann, S. and Lücke, A. and Schmidt, Wolf Gero and Tegenkamp, C.}}, issn = {{1098-0121}}, journal = {{Physical Review B}}, number = {{8}}, title = {{{Interwire coupling forIn(4×1)/Si(111) probed by surface transport}}}, doi = {{10.1103/physrevb.92.085426}}, volume = {{92}}, year = {{2015}}, }
