Query: Energy Exchange between Phononic and Electronic Subsystem Governing The
  Nonlinear Conduction in DCNQI$_2$Cu   We present a dynamical study on the nonlinear conduction behaviour in the
commensurate charge-density-wave phase of the quasi-one-dimensional conductor
DCNQI$_2$Cu below 75 K. We can accurately simulate magnitude and
time-dependence of the measured conductivity in response to large voltage
pulses by accounting for the energy exchange between the phononic and
electronic subsystems by means of an electrothermal model. Our simulations
reveal a distinct non-equilibrium population of optical phonon states with an
average energy of E$_{ph}$ = 19 meV being half the activation energy of about
$\Delta$E$_a$ = 39 meV observed in DC resistivity measurements. By inelastic
scattering, this hot optical phonon bath generates additional charge-carrying
excitations thus providing a multiplication effect while energy transferred to
the acoustic phonons is dissipated out of the system via heat conduction.
Therefore, in high electric fields a preferred interaction of charge-carrying
excitations with optical phonons compared to acoustic phonon modes is
considered to be responsible for the nonlinear conduction effects observed in
DCNQI$_2$Cu.
