What is a band gap?
The space between two energy bands in a solid
The difference in energy between two neighbouring atoms
The distance between two planes of atoms in a crystal
The density of states in a solid
Which of the following statements is true about semiconductors?
They have a very small band gap
They are good conductors of electricity
Their electrical conductivity can be controlled by doping
They are only used in electronic devices that require low power consumption
Which of the following is a common method for growing single crystals of a solid material?

What is solid-state physics?
Solid state physics is a branch of condensed matter physics that studies the physical properties of solid materials, especially their electronic, magnetic, and optical properties. It deals with the behaviour of large numbers of atoms and molecules in solids, and their interactions with external stimuli, such as temperature, pressure, and electromagnetic fields.
What are the technological impacts of solid-state physics?
Solid state physics has played a crucial role in the development of modern technology, including the invention of the transistor, which is the basis for modern electronics, and the discovery of superconductivity, which has important applications in areas such as energy storage and transmission.
What is a unit cell?
The smallest repeating unit of a crystal lattice.
A group of atoms arranged in a specific pattern.
A type of crystal defect.
A type of impurity in a crystal.
Which of the following crystal systems has the highest degree of symmetry?
Triclinic
Orthorhombic
Tetragonal
Cubic
Which of the following is NOT a type of crystal lattice?
Simple cubic
Face-centred cubic
Body-centred cubic
Octahedral cubic
