We present atomistic computations within an empirical pseudopotential framework for the electron $s$-shell ground state $g$-tensor of embedded InGaAs quantum dots (QDs). A large structural set consisting of geometry, size, molar fraction and strain variations is worked out. The tensor components are observed to show insignificant discrepancies even for the highly anisotropic shapes. The family of $g$-factor curves associated with these parameter combinations coalesce to a single universal one…
