Question
100%
The end to end resistance of a connecting bar 10um long, 3 um wide, 1um think, made of various materials. The designer considers:
- Intrinsic silicon at room temperature. Assume that n_i = n = p = 1.5 * 10 ^10 cm^-3
- N-doped silicon with N_D = 5*10^16 per cm^3
- N-doped silicon with N_D = 5*10 ^18 per cm^3
- P-doped silicon with N_A = 5*10^16 per cm^3
- Aluminum with resistivity (p) of 2.8 u Ohms * cm
Find the resistance, R, in each case. For intrinsic silicon, u_n = 1350 Cm^2 / V*s and u_p = 480 cm^2 / V*s. For doped silicon, assume u_n = 3u_p = 1200 cm^2 /V*s
