Query: Formation of the Bielectron in a 2D System due to Spin-Orbit Interaction
  and Image Forces   It is shown that two electrons located in a quantum well near a metal
electrode attract each other due to the spin-orbit interaction (SOI) of the
Bychkov-Rashba type and the electrostatic image forces. Using the example of a
simple model, it is shown that, with quite attainable values of the
characteristic parameters of the system, the effective attraction caused by SOI
prevails over the Coulomb repulsion, and the formation of a bielectron becomes
possible.
