Lattice anharmonicity effects in fluorite oxide single crystals and anomalous increase in phonon lifetime in ceria at elevated temperature
Amey Khanolkar, Saqeeb Adnan, Md Minaruzzaman +6
We investigate the temperature dependence of the frequency and linewidth of the triply-degenerate T zone-centered optical phonon in flux-grown ceria and hydrothermally-synth…
Impact of dynamic Jahn-Teller effect on magnetic excitations, lattice vibration, and thermal conductivity in UxTh1-xO2 system
Saqeeb Adnan, Zilong Hua, Puspa Upreti +11
Vibrational and magnetic properties of single-crystal uranium-thorium dioxide (UxTh1-xO2) with a full range of 0<x<1 is investigated. Thorium dioxide is a diamagnet whose thermal p…
Optical pulse induced ultrafast antiferrodistortive transition in SrTiO3
Saqeeb Adnan, Amey Khanolkar, Shuxiang Zhou +2
The ultrafast dynamics of the antiferrodistortive (AFD) phase transition in perovskite SrTiO3 is monitored via time-domain Brillouin scattering. Using femtosecond optical pulses, w…
Thermal conductivity suppression in uranium-doped thorium dioxide due to phonon resonant scattering
Zilong Hua, Saqeeb Adnan, Amey R. Khanolkar +7
In this work, the thermal transport properties of thorium dioxide (ThO, thoria) with low levels of substitutional uranium (U) doping are explored. We observe strong indications…
Implications of phonon anisotropy on thermal conductivity of fluorite oxides
Saqeeb Adnan, Miaomiao Jin, Matthew S Bryan +3
Fluorite oxides are attractive ionic compounds for a range of applications with critical thermal management requirements. In view of recent reports alluding to anisotropic thermal…
Electrically controlled heat transport in multilayer graphene
Pietro Steiner, Saqeeb Adnan, Muhammed Said Ergoktas +13
The ability to control heat transport with electrical signals has been an outstanding challenge due to the lack of efficient electrothermal materials. Previous attempts have mainly…
