Not at all!
An example from physics: There are two types of semiconductors: n-type and
p-type. Each have a certain structure: n-type semiconductors form the
current by a flow of negative (n-type) electrons, i.e. there are
elementary particles flowing through the semiconductor. p-type
semiconductors form the current by a flow of electron-HOLES! And this is
positive charged, thus p-type.
But the most interesting structures arise, when one type becomes the
environment of the other type. This is where diodes and - MOST important -
