Theory suggests that the determinants of growth at low and high income levels may be different. If countries struggle to transition from growth strategies that are effective at low income levels to growth strategies that are effective at high income levels, they may stagnate at some middle income...

3. From the theoretical transport model, the electron mobility (dashed line) is limited by impurity scattering (red line) at low temperatures. At room temperature, the mobility is limited by the combined effect of the homopolar (out-of-plane) phonon (green line) and the polar-optical phonon...
