What element is a semiconductor? Semiconductors can be pure elements, such as
silicon or germanium
, or compounds such as gallium arsenide or cadmium selenide. In a process called doping, small amounts of impurities are added to pure semiconductors causing large changes in the conductivity of the material.
Is carbon a semiconductor?
Generally, carbon is a semiconductor material
. It’s has four bound electrons in the last orbital because of carbon atom is made covalent bond with others. Pure carbon is exactly semiconductor.
Is boron a semiconductor?
The boron is as well a semiconductor
and the valence electrons are imprisoned by the protons, but the crystal structure is much more complicated so there are long covalent bonds in it. Because of this, compared to silicon, the valence electrons of boron have a larger itinerant range.
Why are group 14 elements semiconductors?
Hint:
These elements have 4 electrons in their valence shell and with an increase in temperature, they create both free electrons and holes for conduction of electricity
. Due to this property, they are widely used in electronics.
What is type of semiconductor?
Semiconductors are divided into two categories:
Intrinsic Semiconductor. Extrinsic Semiconductor
.
A number of the metalloids are semiconductors
as they have intermediate conductivity which is temperature dependent. The ability of the metalloids to conduct electricity and heat is far better than the nonmetals, for example, diamond , which are insulators.
Silicon, a very common element, is used as the raw material of semiconductors
because of its stable structure. Purification of Silicon consumes large amounts of power.
Electrons provide most of the current and are called the majority carrier. When the majority carrier is negative, the material is known as an n-type semiconductor. Since the phosphorus atom has “donated” an electron to the conduction band,
phosphorus is called the donor material
.
The easiest would be judging form the periodic table. If the dopant has more electrons in the outer shell than the semiconductor material, it’s going to be n-type, and with less electrons in the outer shell, it’s p-type.
Detailed Solution. Semiconductors are those elements which have less conductivity than a conductor but more conductivity than an insulator.
Krypton
is a member of the noble gases elements and thus it is not a semiconductor.
NiO nanoparticles are highly robust and feature a broad direct band gap of (3.56 eV). They are also
p-type semiconductors
and can be both super-paramagnetic and superanti-feromagnetic [16].
Germanium is a chemical element with the symbol Ge and atomic number 32. It is a lustrous, hard-brittle, grayish-white metalloid in the carbon group, chemically similar to its group neighbors silicon and tin.
Pure germanium is a semiconductor
with an appearance similar to elemental silicon.

Group 4 is the second group of transition metals in the periodic table. It contains the four elements
titanium (Ti), zirconium (Zr), hafnium (Hf), and rutherfordium (Rf)
. The group is also called the titanium group or titanium family after its lightest member.
The silicon wafers or platforms that serve as the foundation of microchips are composed of silicon, while the metal wires used to connect the sections of circuitry are made of
aluminum or copper
.
A semiconductor product is
the final or intermediate form of an incorporated circuit in a chip
. It has an electronic function. The topography is the design of the layout, that is, the three-dimensional location of elements and interconnections of an integrated circuit.
Metalloids are semiconductors because
they are neither good nor poor conductors
. The valence electrons of metals are not bound to any particular atom. The electrons are free to move throughout the whole solid. Since the electrons are the conductors of electricity, metals are good conductors.
Silver is a conductor
. It is known that the conductivity of any element depends upon the movement or flow of electrons within it.
Most transistors are made from very pure silicon, and some from germanium, but certain other semiconductor materials are sometimes used
. A transistor may have only one kind of charge carrier, in a field-effect transistor, or may have two kinds of charge carriers in bipolar junction transistor devices.
