Concept Introduction:
Semiconductors are the substances that have electrical conductivity between conductors and insulators such as materials of silicon and germanium.
p-type semiconductors are those that have positive charge of holes in large concentration than the electrons. In this, majority carriers are holes and minority carriers are electrons. It is formed by doping trivalent elements that have 3 valence electrons with group 14 elements.
n-type semiconductors are those that have electrons in large concentration than the holes. In this majority carriers are electrons and minority carriers are holes. It is formed by doping pentavalent elements that have 5 valence electrons with group 14 elements.

Chemical Principles: The Quest for Insight
- If an ionic solid has an fcc lattice of anions (X) and all of the tetrahedral holes are occupied by metal cations (M), is the formula of the compound MX, MX2, or M2X?arrow_forwardDescribe the structural units in (a) C (graphite) (b) SiC (c) FeCl2 (d) C2H2arrow_forward8.97 The doping of semiconductors can be done with enough precision to tune the size of the band gap in the material. Generally, in order to have a larger band gap, the dopant should be smaller than the main material. If you are a materials engineer and need a semiconductor that has lower conductivity thin pure silicon, what clement or elements could you use as your dopant? (You do not want either an n- or a p- type material) Explain your reasoning.arrow_forward
- Why is the C 60form of carbon called buckminsterfullerene?arrow_forwardA compound of Sn, Cd and P are mixed together to synthesize a semiconductor. The phosphorous atoms reside in the corners and faces of a cube and the Cd and Sn atoms each reside in 1/4 of the tetrahedral holes. Provide the formula for the compound.arrow_forwarddo (b) What is the relationship between the length of the face diagonal and the radius, r, of the atoms in the cell? (Enter a mathematical expression.) face diagonal = (c) How is the radius of the atoms related to do? (Enter a mathematical expression.) r = (d) Gold metal crystals have an FCC structure. The unit cell edge in gold is 0.4078 nm long. What is the radius (in nm) of a gold atom? nmarrow_forward
- 2) Compare and contrast the temperature dependence of the electrical conductivities of a intrinsic (e.g., Si) semiconductor to that of an ionic conductor. What is the main parameter that influences the temperature dependence of these types of materials?arrow_forward!arrow_forward6. Which type of semiconductor (e.g., n-type or p-type) is each of the following systems likely to be? Explain. (a) Arsenic-doped germanium (b) Gallium-doped germanium (c) Silicon-doped germaniumarrow_forward
- Choose the options that would form a p-type semiconductor. Choose all that would make a p-type semiconductor, there may be more than one. Antimony doped with Germanium Germanium doped with Phosphorus Tin doped with Arsenic Silicon doped with Aluminum Arsenic doped with Telluriumarrow_forwardGallium has an orthorhombic structure, with a0 = 0.45258 nm, b0 = 0.45186 nm, and c0 = 0.76570 nm. The atomic radius is 0.1218 nm. The density is 5.904 g cm3, and the atomic weight is 69.72 g mol. Determine (a) the number of atoms in each unit cell; and (b) the packing factor in the unit cell.arrow_forward
