By being more reliable and allowing for miniturisation, transistors replaced which device in electronic devices?
No two electrons in an atom can simultaneously occupy ___ ____ ______ _____.
The same energy state
What word descibes the free movement of electrons in a metal lattice?
Compared to the current, what direction do free electrons roughly travel in a conducting metal lattice?
The opposite direction
When an atom does not have a complete outer shell, it can form what kind of bonds with nearby atoms?
A semiconductor's resistivity lies between that of an insulator and a conductor. As temperature rises in semiconductors, resistance _______.
What is the highest band occupied by electrons called?
The valence band
In a conductor, what do the conduction and valence bands do?
In an insulator, the valence band is full of electrons. Therefore the gap between the bands are _____.
What are ionically bonded molecules?
What did de Broglie proposed that electrons could also be considered as?
In semiconductors, what is the distance between the conduction and valence bands relative to insulators?
Semiconductors have almost filled valence bands. What are the two most common pure semiconductors?
As temperature increases, what does thermal energy allow electrons in the valence band to do?
Cross the gap
What do the electrons leave behind in the valence band?
What direction, relative to the conduction band's current, does this new positive current flow?
The opposite direction
What is the process of adding atoms with a different amount of valence electrons to a semiconductor?
Silicon and Germanium do not need ^ to be a semiconductor. They are known as pure semiconductors. What is another name for them?
Opposite of the above require the addition of dopant atoms. What are these semiconductors called?
What are the two most common dopant atoms? (one each for n-type and p-type)
What shape do groups of silicon atoms form in a diamond lattice structure?

Negative charge carriers
What do p-type semiconductors have more of?
Positive charge carriers
What do thermionic devices use in glass vacuum tubes to control the flow of current.
What are the simplest form of a valves called? (They only have two electrodes)
Due to its simplicity, ^'s unidirectional current means it is used for what simple function?
It can also convert alternating current (AC) into direct current (DC). What is this called?

To get to the other semiconductor, which is the other type, what zone do the electrons travel across?
The depletion zone
What are the main benefits of solid state devices over thermionic devices?
They are smaller
Less heat produced
Lower voltage required
Transistors are semiconductor devices that can act as a switch or as an amplifier. What are the two main types of transistor?
What is a transistor is a combination of?
two n-p junctions
Integrated circuits are tiny electrical circuits used to perform specific electrical functions. What primarily is the issue with wiring that IC's reduce?
What are integrated circuits in computer chips made of?

The Inherently very specific answers required on this quiz makes it very tough!... especially as some questions are ambiguous: "heated filament" probably should be "control grid potential" and "what are the two main types of transistor" could also be answered "bipolar junction transistors and field-effect transistors" :o)

Sorry, but I'm just going off what my Physics textbook tells me. Primarily this quiz is to help me study but comments like that help me understand more. Thank you

No worries! As long as the textbook questions and answers match any test then all good! Happy studying :o)
