By using wavelength modulated absorption (WMA), optical transitions between subbands are revealed in \(\mathrm{a}-\mathrm{Si}: \mathrm{H} / \mathrm{a}-\mathrm{SiN}_{\mathrm{x}}: \mathrm{H}\) superlattices for the well-layer thicknesses less than \(50 \AA\). The threshold energies of the distinct ste
