Doping evolution of the phonon density of states and electron-lattice interaction in Nd${}_{2-x}$Ce${}_x$CuO${}_{4+\delta }$

H. J. Kang, Pengcheng Dai, D. Mandrus +6

We use inelastic neutron scattering to study the evolution of the generalized phonon density of states (GDOS) of the $n$-type high-$T_c$ superconductor Nd${}_{2-x}$Ce${}_x$CuO${}_{4+\delta }$…
