Key Words / FlashCards
Key Words Definitions (pref. in our own words)
Semiconductor Electronic components that exploit the electronic properties of semiconductor materials, principally silicon, germanium, and gallium arsenide, as well as organic semiconductors.
Learning aids / Gadgets
Gadgets How it can be used
microprocessors All transistor types can be used as the building blocks of logic gates, which are fundamental in the design of digital circuits. transistors act as on-off switches; in the MOSFET, for instance, the voltage applied to the gate determines whether the switch is on or off.
Real life uses :

Building circuits.

Places to visit :

Digital circuits.

Practical examples around us
Examples Explainations
Solar cell Electrical device that converts the energy of light directly into electricity by the photovoltaic effect.
What you learn in Theory:

Semiconductor materials are so useful because their behavior can be easily manipulated by the addition of impurities.

What you learn in Practice:

Semiconductor devices have replaced thermionic devices (vacuum tubes) in most applications.
