Electronic & Optoelectronic Properties of
Semiconductor Structures (2008) – Solutions
Manual – Singh
How many elements are there? - answers-118
Atomic Number - answers-the number of protons in the nucleus of an atom
Bohr Model - answers-model of the atom
Maximum number of electrons within a shell - answers-2n^2
valence electrons - answers-Electrons on the outermost energy level of an atom. When it gains
sufficient
energy from an external source, it can break free from its atom. This is the basis for conduction
in materials.
Ionization - answers-The process of losing a valence electron that results in the formation of an
ion
ionization energy - answers-The amount of energy required to remove an electron from an
atom
The escaped valence electron is called a - answers-A free electron
1
, The Quantum Model - answers-uses a mathematical equation to predict the likelihood of an
electron being in a certain position
Wave-particle duality. - answers-the concept that all matter and energy exhibit both wave-like
and particle-like properties
Uncertainly principle. - answers-It's impossible to determine simultaneously both the
position and velocity of an electron with any degree of accuracy or certainty. The result
of this principle produces a concept of the atom with probability clouds
Name the first four atom shells and the amount they can hold. - answers-They are named s, p,
d, and f. s can hold 2 electrons, p can hold 8 electrons, d can hold 18 electrons, and orbital f can
hold 32 electrons.
electron cloud - answers-a region around the nucleus of an atom where electrons are likely to
be found
Using the atomic number to describe a silicon (Si) using an electron configuration table. -
answers-Atomic Number 14. There are 2 electrons in shell s, 8 in shell p and 4 in shell
Define electron - answers-a negatively charged subatomic particle
Name two theories that distinguish the quantum model. - answers-Wave-particle duality and
Uncertainly principle
Electrical Properties of materials - answers-conductors, semiconductors, and insulators.
