recommendations! Published in 2018 at "AIP Advances"

DOI: 10.1063/1.5053174

Abstract: Anharmonic lattice vibration in metallic and semiconducting Sb2Te3 is investigated using temperature dependent Raman spectroscopic studies, synchrotron powder diffraction, and heat-capacity measurements. Thermal variation of structural parameters divulges temperature dependence of structural anisotropy in both… read more here.

DOI: 10.1364/oe.543028

Abstract: The effective control of conductivity in LuFeO3 (LFO) with Co3+ doping is explored by terahertz (THz) time-domain spectroscopy. It is demonstrated that the conductivity of 5% Co-doped LFO (LFO:Co 5%) is lower than that of… read more here.

DOI: 10.3390/axioms14110781

Abstract: Lattice structures find broad application in aerospace, automotive, biomedical, and energy systems owing to their exceptional structural stability. These systems typically exhibit complex internal couplings that facilitate vibration propagation across the entire network. The primary… read more here.
