Undoped InSb Wafer 2 Inch As Cut Wafer Mechanical Polished Type Band structure and carrier concentration of InSb 300 K
Eg = 0.17 eV
EL = 0.68 eV
EX= 1.0 eV

Temperature Dependences

Temperature dependence of the energy gap

Eg = 0.24 - 6·10-4·T2/(T+500) (eV),
where T is temperatures in degrees K (0 < T < 300).
 

Effective density of states in the conduction band

Nc~ 8·1012·T3/2 (cm-3)

Effective density of states in the valence band

Nn ~ 1.4·1015·T3/2 (cm-3).

Intrinsic Carrier Concentration

ni = (Nc·Nν)1/2exp(-Eg/(2kbT))
For 200K < T < 800 K ni = 2.9·1011(2400 - T)3/4 ·(1+2.7·10-4·T)·T3/2 ·exp(-(0.129 - 1.5·10-4T)/(2kbT)) (cm-3)

Effective Masses

Electrons:  
For Γ-valley mΓ = 0.0.14mo
Non-parabolicity:
E(1+αE) = h2k2/(2mΓ)
α = 4.1 (eV-1)
In the L-valley effective mass of density of states mL=0.25mo

 

Holes: mh = 0.43mo
Heavy mh = 0.43mo
Light mlp = 0.015mo
Split-off band mso = 0.19mo
Effective mass of density of states mv = 0.43mo
