Journal ArticleDOI
Infrared and Raman-scattering studies in single-crystalline GaN nanowires
Hsiang Lin Liu,Chia Chun Chen,Chih Ta Chia,Chun Chia Yeh,Chun Ho Chen,Ming Yuan Yu,Stacia Keller,Steven P. DenBaars +7 more
TL;DR: In this paper, the spectral properties of high-purity and high-quality GaN nanowires have been investigated in terms of the peak shift and the broadening of the four first-order Raman modes.
Journal ArticleDOI
Correlation of microwave dielectric properties and normal vibration modes of xBa(Mg1/3Ta2/3)O3-(1-x)Ba(Mg1/3Nb2/3)O3 ceramics: II. Infrared spectroscopy
TL;DR: In this paper, the relationship between the microwave dielectric properties and the IR active phonons of xBa(Mg1/3Ta2/3)O3-(1−x)Ba(mg 1/3Nb2/)O3 ceramics was investigated.
Journal ArticleDOI
Micro-Raman spectroscopy of a single freestanding GaN nanorod grown by molecular beam epitaxy
TL;DR: In this article, a single freestanding GaN nanorod was grown by molecular beam epitaxy, and the angle-dependent Raman spectra were measured on a single GaN.
Journal ArticleDOI
Self-assembled nanorings in Si-capped Ge quantum dots on (001)Si
TL;DR: In this article, the formation of nanorings is attributed to alloying and strain relief in the Si/Ge/(001)Si system, and self-assembly of nanors provides a useful scheme to form ultrasmall ring-like structure and facilitates the characterization of the physical properties of unconventional quantum structures.
Journal ArticleDOI
Microwave dielectric relaxation in cubic bismuth based pyrochlores containing titanium
Hong Wang,Stanislav Kamba,Huiling Du,Meiling Zhang,Chih Ta Chia,S. Veljko,S. Denisov,Filip Kadlec,Jan Petzelt,Xi Yao +9 more
TL;DR: In this article, the authors showed that the microwave dielectric relaxation originates in hopping of disordered Bi and part of Zn atoms in the A sites of the pyrochlore structure, i.e., increasing x, results in an increase of microwave permittivity from 150 to 200 of the relaxation frequency and also of the microwave quality.
