- We report inelastic neutron scattering measurements of the phonon spectra in a pure powder sample of the multiferroic material BiFeO3. A high-temperature range was covered to unravel the changes in the phonon dynamics ac...
- Design of ductile bulk metallic glasses by adding "soft" atoms
[作者:Zheng, N; Qu, RT; Pauly, S; Calin, M; Gemming, T; Zhang, ZF; Eckert, J,期刊:Applied Physics Letters, 页码:141901-141901 , 文章类型: Article,,卷期:2012年100-14]
- We propose a strategy for the design of ductile bulk metallic glasses (BMGs) through minor substitution using relatively large atoms, which make the bonding nature become more metallic and with it less shear resistant. S...

- Electron spin dephasing and relaxation due to hyperfine interaction with nuclear spins is studied in an InAs/GaAs quantum dot ensemble as a function of temperature up to 85 K, in an applied longitudinal magnetic field. T...
- Coaxial nanowire resonant tunneling diodes from non-polar AlN/GaN on silicon
[作者:Carnevale, SD; Marginean, C; Phillips, PJ; Kent, TF; Sarwar, ATMG; Mills, MJ; Myers, RC,期刊:Applied Physics Letters, 页码:142115-142115 , 文章类型: Article,,卷期:2012年100-14]
- Resonant tunneling diodes are formed using AlN/GaN core-shell nanowire heterostructures grown by plasma assisted molecular beam epitaxy on n-Si(111) substrates. By using a coaxial geometry, these devices take advantage o...
