AB - <p style="text-align: justify;">We investigate the validity of stationary simulations for semiconductor quantum charge transport in a one-dimensional resonant tunneling diode via fluid type
models. Careful numerical investigations to a quantum hydrodynamic model reveal
that the transient simulations do not always converge to the steady states. In particular,
growing oscillations are observed at relatively large applied voltage. A dynamical bifurcation is responsible for the stability interchange of the steady state. Transient and
stationary computations are also performed for a unipolar quantum drift-diffusion
model.</p>
