Weak localization was observed in gallium manganese arsenide (Ga,Mn)As nanowire arrays at millikelvin temperatures. Spin-orbit interaction effects were also noted, influencing electron phase coherence.

Area of Science:

  • Condensed matter physics
  • Spintronics
  • Low-temperature physics

Background:

  • Semiconductor nanowires offer unique platforms for exploring quantum phenomena.
  • (Ga,Mn)As is a prominent ferromagnetic semiconductor with potential for spintronic applications.

Purpose of the Study:

  • To investigate quantum transport phenomena in (Ga,Mn)As nanowire arrays.
  • To characterize the phase coherence length and spin-orbit interaction effects.

Main Methods:

  • Fabrication and measurement of (Ga,Mn)As nanowire arrays.
  • Low-temperature electrical transport measurements at millikelvin temperatures.
  • Analysis of magnetoresistance to identify weak localization and antilocalization effects.

Main Results:
