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…

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…

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…
