2D, two-dimensional.

Carrier types ‘e’ and ‘h’ denote ‘electron’ and ‘hole’, respectively. NL represents the number of layers, mx* and my* are carrier effective masses for directions x and y, respectively, E1x (E1y) and Cx_2D (Cy_2D) are the deformation potential and 2D elastic modulus for the x (y) direction. Mobilities μx_2D and μy_2D were calculated using equation (1) with the temperature T set to 300 K.
