Semiconductors!!
Silicon and germanium semiconductors are most commonly used in memory and logic chips.
Metalloids or semiconductors
The three major categories of elements on the periodic table are metals, nonmetals, and metalloids. Metals are typically shiny, malleable, and good conductors of heat and electricity. Nonmetals are generally poor conductors of heat and electricity, and can be solid, liquid, or gas at room temperature. Metalloids have properties that are intermediate between metals and nonmetals.
Group 14 elements, mainly silicon or germanium are semiconductors. If they are dopped with group 13 elements such as gallium / indium or with group 15 elements such as arsenic / antimony, then the conducting ability increases.
Silicon and germanium are among the widely used semiconducting elements.
Commonly doped silicon is used to make semiconductors, but advancements in organic electronics now mean that semiconductors can be made from molecules made from elements such as carbon, hydrogen, oxygen, sulphur, nitrogen and a few others.

Elements of group 4a are used as semi-conductorse.g. silicon,germanium etc.

Silicon is the main component of most semiconductors used today.
Most semiconductors are elements with 4 valence electrons:carbon as either diamond or nanotubes, still has process problemssilicon, most preferred nowgermaniumThere are also binary semiconductors made of alloys of elements with 3 & 5 valence electrons:gallium arsenide is used in some very high speed electronicsaluminum indium gallium phosphide is used in some LEDs and solid state LASERsetc.There are also less commonly used semiconductors used in special purpose applications:copper oxide used to be used in high voltage rectifiers in low cost vacuum tube electronicsselenium is used in light sensitive drum in photocopiers and laserprinterslead sulfide (galena) used in crystal radiosetc.
