What does germanium do?
Germanium does no "do" anything.
Is germanium a conductor or an insulator?
neither, germanium is a semiconductor
What are two reasons why density is a useful property for identifying substances?
Density is specific for each substance. Also the measurement is generally simple.
What family is germanium in?
The Carbon Family
Is germanium a conductor or a insulator?
conductor
What is the specific resistance of pure silicon?
55k ohm-cm
How can you get a pure sample of germanium?
Pure germanium is obtained by distllation of germanium tetrachloride, followed by hydrolysis of GeCl4 to GeO2 and reducing of GeO2 with hydrogen to Ge.
Is gold a better conductor than germanium?
Yes. Pure gold is a much better conductor than pure germanium is.
What are pure semiconductors?
silicon and germanium
Is germanium n type semiconductor?
Pure germanium is neither n or p. When doped with impurities it can be either.
When a potential is applied to pure germanium in what direction do the electrons and holes move?
in pure germanium there are effectively noconduction band electrons or holes, so they don't move at all.
Is germanium formed naturally?
Germanium is a naturally occurring element, but does not occur in pure form on the Earth (only in compounds).
Does germanium form a monatomic or diatomic in pure form?
Neither, it is a crystalline solid in pure form.
When a piece of copper and another of germanium are cooled from room temperature to 800 K then the resistance?
Each of them increases
What kind of odor does germanium have?
The pure element has no odor as it is a solid and nonvolatile.
How Many subatomic particles does germanium have?
Germanium has 32 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a germanium isotope = Mass number - 32
Are there any pure forms of semi conductors other than germanium and silicon?
gaAs is semiconductor
