Electronic redistribution triggered by an external electric field pointing along nanowires axis is an important issue due to its potential applications. Few researchers have addressed this problem because when realistic sizes and doping levels are considered, the many-body electron-electron interactions becomes highly complex. In this contribution, we present a systematic study of the effect of such an electric field on micrometer-long GaAs/AlGaAs nanowires withn-doping levels around 1018electrons/cm3. Our method is based on the derivation of a real-space effective potential that considers a Yukawa-like electronic interaction. One of our most important findings is related to the spatial stability of the Wigner molecule under the external field, where the electronic charge is displaced on pinning positions. This discovery is very promising for the realization of valuable architectures based on the quantized electronic distributions in technological areas such as nanoelectronics or spintronics or as electric sensors at the nanoscale. © 2021 American Chemical Society
