Abstract
- Modulation of thermal conductivity has become a hotspot in the field of heat conduction. A novel strategy based on targeted phonon excitation has been recently proposed for efficient and reversible modulation of thermal conductivity. In this article, the effectiveness of that strategy is further evaluated on hexagonal boron nitride through ab initio methods. Results indicate that thermal conductivity can be increased from 885 W m-1 K-1 to 1151 W m-1 K-1 or decreased to 356 W m-1 K-1, thereby broadening the scope of applicability of this strategy.<br />Comment: 12 pages, 3 figures
