Erratum: Current and Strain-Induced Spin Polarization in<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi>InGaN</mml:mi><mml:mo>/</mml:mo><mml:mi>GaN</mml:mi></mml:math>Superlattices [Phys. Rev. Lett.<b>98</b>, 136403 (2007)]
The lateral current-induced spin polarization in InGaN/GaN superlattices (SLs) without an applied magnetic field is reported. The fact that the sign of the nonequilibrium spin changes as the current reverses and is opposite for the two edges provides a clear signature for the spin Hall effect. In addition, it is …
