Exam 1: Fundamental Solid-State Principles

As a result of covalent bonding, intrinsic silicon effectively acts as a/an

Conduction through a material with a positive temperature coefficient tends to as temperature increases.

P-type materials are electrically in their natural state.

Trivalent atoms are often referred to as

In a p-type material, the minority carriers are

When a pn junction is forward biased, the depletion layer is at its width and the device acts as a near-perfect .

Pentavalent elements have valence electrons).

N-type materials are electrically in their natural state.

The difference between the energy levels of two orbital shells is called the

When trivalent elements are used in doping, the resulting material is called material and has an excess of .

The small amount of current that is present at the forming of a pn junction is called

The time between the forming of an electron-hole pair and recombination is called

The voltage across a forward-biased germanium pn junction is approximately

The simplest model of the atom is called the

-What type of junction bias is shown?

Why is silicon more commonly used than germanium in the production of solid-state components?

Which of the following is a result of covalent bonding in intrinsic silicon?

Which of the following is not a trivalent doping element?

When a pn junction is reverse biased, its resistance is

A p-type material is joined with an n-type material. When forward biased, the voltage across the junction is approximately 700 mV 0.7 V). The two materials are most likely made of
