Although we refer to the layers within such materials as ‘2D’, they are …
Taking a multiband approach explains ‘electron-hole reverse drag’ and exciton formation Mystifying experimental results obtained independently by two research groups in the USA seemed to show coupled holes and electrons moving in the opposite direction to theory.
