Resonances in the one-dimensional Dirac equation in the presence of a point interaction and a constant electric field [PDF]
, 2005 We show that the energy spectrum of the one-dimensional Dirac equation in the presence of a spatial confining point interaction exhibits a resonant behavior when one includes a weak electric field.

Poling of VDF/TrFe copolymers using a step-wise method [PDF]
, 1996 A new poling technique is presented, in which a series of five consecutive pulses of electric field, and with successively increasing strength is applied between the two electrodes of 65/35 VDF/TrFE copolymer based sensor. Between each pulse, the applied
