• Direct calculation of modal contributions to thermal conductivity via Green–Kubo modal analysis (2015, background): “Such a simplification is useful, because very often there may be a group of modes that are of primary interest, and individual mode level detail can be targeted on such groups, while other modes such as optical modes, which are known to have minimal contributions to the thermal conductivity [1], can”
• Heat Transfer in Thermoelectric Materials and Devices (2013, background): “Besides, the accurate modeling of intrinsic phonon lifetimes from first-principles calculations [125,173], the importance of optical phonons in nanowires [173], the core defects, and the surface oxide layer [170] should also be considered.”
