For example:
· If I doped donor atoms at one end and acceptor atoms at the other end of a silicon crystal, it would have both P-type and N-type regions and there would be a junction between them.
· If free electrons and holes moved in a controlled manner, they wouldn't wander freely in the lattice.
I wish I determined…
wish + Past
For example:
· I wish I measured these parameters more carefully.
(=I don't measure them carefully)
· I wish I could gain the higher results. (I can't)
Remember:
If I were/if I was
I wish it were/I wish it was
For example:
· If I were you, I would correct this test.
or If I was you, …
· I wish it were possible.
(III) If-clause (If I had designed …, they would have set up … )

(but it didn't lose a positive charge)
I wish I had designed…

For example:
· I wish I had constructed my replica. I would have used it now. (but I didn't construct it)
· I wish I had corrected some measurements in my laboratory work. I would have obtained a higher result. (but I didn't correct them)
