"controls spin degree of freedom/ electron filling sequence, through trigonal warping effect, applying small perpendicular electric field, where s-shell filled with 4 electrons, 2 spin-up/ 2 spin-down, each from opposite valleys... when electric field increased, s-shell's electron holding capacity expanded to 12, with first 6 having same spin polarization... minivalley degree of freedom could electrically manipulate spin degree of freedom, increasing quantum control/ electron state manipulation... quantum computing, electronics"
