3 Terms and Definitions

Terms and definitions GB/T 14264 apply to this document defined.

4 principle of the method

The use of the carrier concentration and temperature variation of electrical neutrality equation, n (P) -Tl curve fitting analysis by computer, thus To obtain the degree of compensation. Neutral equation (N type in a sample, for example) as shown in Formula (1). n (n NA) ND-NA-n = NC gA · Exp (-Ej/kT) (1) Where NC is calculated, see formula (2). NC = 2 2πm * akT (2) Ionized impurity concentration dependence see equation (3). n300 = ND-NA (3) By the formula (1), (2), (3) using the principle of least squares, and appropriate adjustments gA, m * a, ND, NA, Ej5 quantities for data fitting to give The degree of compensation to see the expression of formula (4), (5). Kp = ND/NA (P) type (4) KN = NA/ND (N) type (5) According to GB/T 4326, the samples undergo a variable temperature Hall measurements, test data calculated by the formula (6) to give nT-1 curve. n = γ/e · RΗ (6) Formula (1) to (6). N --- carrier concentration, units per cubic centimeter (cm-3); NA --- acceptor impurity concentration, atoms · cm-3; ......
