lies in its small size and its amazingly small power consumption. On the other hand,
today's transistors have an upper frequency limit that is lower than that of electron
tubes.

        2.8.7 Translate the word-combinations

different means, conduction by holes, mutually opposed particle flow, power
consumption, upper frequency limit, conduction mechanism, excess holes, excess
electrons, transistor interaction.

        2.8.8 Answer the questions

1. What is of primary interest in vacuum tubes? 2. What does current consist of
when voltage is applied? 3. Where does transistor interaction occur in
semiconductors? 4. What are transistors analogous to in application? 5. What does the
attractiveness of the transistor lie in?

        2.8.9 Form adverbs from the following adjectives, translate them

primary, mutual, different, distinct, amazing, common, excessive.

        2.8.10 Form sentences from these word combinations

The semiconductor materials           is of primary interest
In application transistors            in the region where excess
                                      electrons control excess holes
The control of free electrons         is of basic concern in transistors
In germanium and silicon              are almost analogous to vacuum
tubes
Transistor interaction oc-             conduction is caused by excess
curs in semiconductors                 electrons or excess holes

        2.8.11 Learn the dialogue by heart

A.   Would you mind telling me the following: “What do you deal with in your work?”
B.   I deal with semiconductors and transistors in my work.
A.   Can you tell me what a semiconductors is? Is it a material or a device?
B.   Don’t you know it? It is a material.
A.   Can you name any semiconductors?
