We identify dot sizes and shapes for which one in-plane component of the g tensor changes sign for realistic electric fields, and show this should permit full Bloch-sphere control of the electron spin in the quantum dot using only a static magnetic field and a single vertical electric gate.4 pages, 3 figuresMesoscale and Nanoscale PhysicsMaterials Sciencetext
