Phonon Confinement Effect on Lattice Thermal Conductivity of Zn4Sb3 Quantum Well Structure	2017	11	.pdf	application/pdf	3409	184	60	The reduction is mostly due to the drop in the average group velocity caused by the spatial confinement of acoustic phonons and the corresponding increase in phonon relaxation rates. The system algebraic acoustic-wave equations (Eqs.(6) and (7)) may be solved by the numerical approach, and phonon group velocity is calculated for each branch via numerical differentiation.	cache/iajs-993.pdf	txt/iajs-993.txt
