A) \[{{({{E}_{g}})}_{C}}>{{({{E}_{g}})}_{Si}}\]
B) \[{{({{E}_{g}})}_{C}}={{({{E}_{g}})}_{Si}}\]
C) \[{{({{E}_{g}})}_{C}}<({{E}_{g}})Ge\]
D) \[{{({{E}_{g}})}_{C}}<{{({{E}_{g}})}_{Si}}\]
Correct Answer: A
Solution :
Carbon, silicon and germanium are semiconductors. |
\[{{({{E}_{g}})}_{C}}=5.2\,eV\] |
\[{{({{E}_{g}})}_{Si}}=1.21\,eV\] |
\[{{({{E}_{g}})}_{Ge}}=0.75\,eV\] |
Thus, \[{{({{E}_{g}})}_{C}}>{{({{E}_{g}})}_{Si}}\] and \[{{({{E}_{g}})}_{C}}>{{({{E}_{g}})}_{Ge}}\] |
Note: Elements carbon, silicon and germanium are found in IVA group of periodic table. |
