The spin gap can be written as(1) Δ s = g 0 μ B B + E ex = g * μ B B , where Eex is the many-body exchange energy which lifts the g-factor from its bare value ( ...

In order to obtain the spin gap Δs, we measure the spin-split longitudinal resistivity minimum which shows an activated behavior. From the spin gaps at ...

We have performed magnetotransport measurements of the electron g factor in a two-dimensional GaAs electron gas. In order to obtain the spin gap ...

We note that band gaps and lattice constants depend on temperature. This is taken into account automatically for each temperature sweep. The following figure ...

Mar 25, 2013 · In this paper, we report a method to directly measure the spin gaps in two-dimensional electron gases (2DEGs), in which the electrons are usually confined in ...

Jan 22, 2013 · Al2O3 is a widely used oxide and is also one of the best insulating materials in nature, with a band gap normally above 8.0 eV. The synthesis of ...
