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. \[{{(Eg)}_{C}}=5.2\,eV\] \[{{(Eg)}_{Si}}=1.21\,eV\] \[{{(Eg)}_{Ge}}=0.75\,eV\] Thus, \[{{(Eg)}_{C}}>{{(Eg)}_{Si}}\]and \[{{(Eg)}_{C}}>{{(Eg)}_{Ge}}\]You need to login to perform this action.
