Table 3. Hf₂CO₂ carrier mobility.

Carrier type			E1x	E1y	Cx	Cy	μx	μy
			(eV)		(Jm−2)		(103 cm2V−1s−1)
e	0.231	2.162	10.57	7.101	293.6	291.0	0.329	0.077
h (upper)	0.423	0.164	7.636	2.297	293.6	291.0	0.924	26.0
h (lower)	0.164	0.414	2.023	7.422	293.6	291.0	34.3	1.00

Carrier types “e” and “h” denote “electron” and “hole,” respectively. and are the effective masses along the zigzag (x-) and armchair (y-) directions, respectively. E_1x and E_1y are the deformation potential constants, and C_x and C_y are the elastic moduli. μ_x and μ_y are the room-temperature carrier mobilities.
