f) … the first semiconductor electronic devices.

g) … electronic circuits on one small plate of semiconductor material.

h) … a limiter of the electrical current that flows through a circuit.

i) … the key active component in practically all modern electronics.

13. Read the text and choose the word that best fits each space. Put the correct letter (a, b, c or d) for each sentence.

The semiconductor diode can perform a wide variety of 0-… and is one of basic electronic servants. To understand how a semiconductor 1-… works, let's go back a little and examine 2-… itself. An electric 3-… is simply another name for a flow of electrons — the basic electrical charge found in all elements. Electricity flows when 4-… move from one atom of a substance to the next. In some materials, like copper, silver, aluminium and many other metals, the 5-… can move easily, and it is because of metals conducting electrons so easily that they are called 6-… .

In other materials— glass, porcelain, rubber, and many plastics— the 7-… can move only with great difficulty. In fact, only very few electrons can move at all in these substances, even under great electric 8-… ; and so the flow of electric current through them is blocked. These substances are called insulators. Between 9-… and insulators are many materials which are neither good conductors nor good insulators. The 10-… of their atoms are free to move, but are not so free as in a conductor.
