Lecture 1 Flashcards
Made of a semiconductive material.
Diodes, transistors, and integrated circuits (IC)
Formed when two different types of semiconductive material are joined.
PN junction
The science that deals with the development and application of devices and systems involving the flow of electrons in vacuum, in gaseous media, plasma and in semiconductors.
RA 5734, Sec. 21 C
The science dealing with the development and application of devices and systems involving the flow of electrons or other carriers of electric charge, in a vacuum, in gaseous media, in plasma, in semiconductors, in solid-state and/or in similar devices, including, but not limited to, applications involving optical, electromagnetic and other energy forms when transduced or converted into electronic signals.
RA 9292, Sec. 3 H
Introduced by Thomas Edison and John Ambrose Fleming in 1904.
Two-electrode vacuum tube

Thomas Alva Edison
Commercial TV began
1946
First vacuum tube computer was built at the University of Pennsylvania.
1943
Introduction of point-contact transistor by Walter H. Brattain and John Bardeen at Bell Telephone Laboratories.
December 23, 1947
Complex combination of several kinds of devices on a common base, called substrate. Invented by Jack Kilby of Texas instruments.
Integrated Circuits
This includes AM and FM radio, television, and satellite communication.
Communication Electronics
Electronics play an important role in the control and monitoring of electrical systems as in power plants, refineries, etc.
Electric Power
The circuits for digital applications operate with pulse of voltage or current.
Digital Electronics
Applied to cars for changing battery, measuring gauges and monitoring of engine performances.
Automotive Electronics
Includes control of heating and welding processes, the use of elevator’s control, operating of copying machines, automatic door openers and burglar alarms.
Industrial Electronics
Combines electronics with biology, medical research, diagnosis and treatment, all use electronic equipment.
Medical Electronics
Smallest particle of an element that possesses the unique
characteristics of that element.
Atom
All matter is composed of?
Atoms
All atoms consist of electrons,
protons, and neutrons except?
Normal hydrogen
He proposed that the electrons in an atom circle the nucleus in
different obits, similar to the way planets orbit the sun in our solar
system.
Niels Bohr
The Bohr model is often referred to as the?
Planetary model
According to this model, atoms have a planetary type of structure that consists of a central
nucleus surrounded by orbiting electrons.
Bohr model
The nucleus consists of positively charged particles called
Protons
