Multi-ion ionized impurities scattering, acoustic and polar optic phonons are considered as scattering mechanisms. The calculated values of mobility are compared to known experimental data for bulk (3D) n-and p-type wurtzite, n-type zinc-blende GaN crystals and low dimensional (2D and 1D) ternary GaAlN compounds. The resulting analytical expressions give the dependences of mobility on dimensionality of charge carrier gas, its density, effective mass, temperature and confining dimensions. A comparison of the experimental and calculated temperature dependences of the mobility in bulk GaN crystals (3D) and in AlGaN\/GaN nanowires (1D) shows that the mobility at\n                    <jats:inline-formula>\n                      <jats:tex-math>\n                        \n                      <\/jats:tex-math>\n                      <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" overflow=\"scroll\">\n                        <mml:mrow>\n                          <mml:mi>T<\/mml:mi>\n                          <mml:mo>&gt;<\/mml:mo>\n                          <mml:mn>100<\/mml:mn>\n                          <mml:mstyle scriptlevel=\"0\"\/>\n                          <mml:mrow>\n                            <mml:mtext>K<\/mml:mtext>\n                          <\/mml:mrow>\n                        <\/mml:mrow>\n                      <\/mml:math>\n                    <\/jats:inline-formula>\n                    is determined by the scattering of charge carriers by polar optical phonons with an energy of 91.2 meV.
