Clathrates represent a fascinating class of inorganic materials with a unique structural motif:
3D framework with large polyhedral cages encapsulating guest ions. Weak electrostatic …

Thermoelectric clathrates hold significant promise for high temperature applications with zT
values exceeding 1.3. The inorganic clathrates have been shown to be both chemically and …

Recently, liquid-like superionic thermoelectric materials have attracted great attention due to
their extremely low lattice thermal conductivity and high thermoelectric figure of merit (ZT) …

We investigate the role of the quartic anharmonicity in the lattice dynamics and thermal
transport of the type-I clathrate Ba 8 Ga 16 Ge 30 based on ab initio self-consistent phonon …

The underlying mechanism of common limited lattice thermal conductivity (κ) in energy-
related host–guest crystalline compounds has been an ongoing topic in recent decades …

We report structural, transport, and thermal properties of carrier-tuned Ba 8 Ga 16 Sn 30
single crystals with the type-1 clathrate structure (β phase), demonstrating that Ba 8 Ga 16 …

The ability to control the transport of thermal energy is critical in a wide variety of
technologies. At the same time, understanding the underlying microscopic mechanisms of …

Phonon-glass electron-crystal (PGEC) behaviour is realised in La0. 5Na0. 5Ti1− xNbxO3
thermoelectric oxides. The vibrational disorder imposed by the presence of both La3+ and …

Recent discoveries of materials with ultralow thermal conductivity open a pathway to
significant developments in the field of thermoelectricity. Here, we conduct a comparative …
