Question

Points Save Answer Determine the electron concentration in units of

(cm ⁻ ¹³) in a semiconductor. Assume complete ionization and the
parameters given below: .
• Semiconductor: Silicon
ND = 6 x 10¹² (cm⁻¹³)
NA = 6 x 10¹⁵ (cm⁻¹³)

Answer 1

The electron concentration in a semiconductor can be determined using the formula ne = |ND - NA|. Given ND = 6 x 10^12 cm^-13 and NA = 6 x 10^15 cm^-13, the electron concentration is 5.994 x 10^15 cm^-13.

Step-by-step explanation:

The electron concentration in a semiconductor can be determined using the formula:

ne = |ND - NA|

Where:

ne = electron concentration (in cm-13)

ND = donor concentration

NA = acceptor concentration

Given:

ND = 6 x 1012 cm-13

NA = 6 x 1015 cm-13

Using the formula, we have:

ne = |6 x 1012 - 6 x 1015|

= 6 x 1015 - 6 x 1012

= 5.994 x 1015 cm-13

Therefore, the electron concentration in the semiconductor is 5.994 x 1015 cm-13.
