Vedclass · Answer

(C) $1$. The property of being transparent to visible light indicates that the material has a large band gap,which is characteristic of insulators or semiconductors.$2$. The property that electrical conductivity increases with temperature is a defining characteristic of semiconductors.$3$. Semiconductors like Silicon $(Si)$ and Germanium $(Ge)$ are formed by covalent bonds between atoms.$4$. In these materials,as temperature increases,more electrons gain enough thermal energy to jump from the valence band to the conduction band,thereby increasing conductivity.$5$. Therefore,the correct answer is covalent bonds.

$LIST$ $I$	$LIST$ $II$
$A$. Intrinsic Semiconductor	$I$. Fermi-level near conduction band
$B$. $n$-type semiconductor	$II$. Fermi-level at middle
$C$. $p$-type semiconductor	$III$. Fermi-level near valence band
$D$. Metals	$IV$. Fermi-level inside conduction band

$A$ solid which is transparent to visible light and whose electrical conductivity increases with temperature is formed by:
