We find that differences between exciton energies in abrupt quantum wells and wires are very significant (up to similar to 150 meV), depending on the polytype and the thickness of the nonabrupt, SiC/SiO2 interfaces. The exciton blueshift due to a 5 Angstrom wide nonabrupt interface is very strong (up to similar to 120 meV).
