Webthe top Si -doped layer to the upper end of the InAlAs and l 1=150 nm the distance between the two Si -doped layers; B=14.2 is the relative dielectric constant of InGaAs 6 and V B is the offset of the fermi level at the InGaAs surface with respect to the conduction band edge. In the denominator, z is an effective “quantum” depth of the 2DEG ... Webelectron mass. The heavy hole effective mass, mhh, is typically more comparable to the free electron mass (mhh ~ 0.35 mo for the most common situation in quantum wells), and does not vary systematically with the band gap energy. Quantum wells are one example of heterostructures - structures made by joining different
