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 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.

If I had determined a fault, I would have corrected it. (but I didn’t determine it)
If one region had lost a positive charge, the other region would have gained it. (but it didn’t lose a positive charge)
I wish I had designed…
wish + Past Perfect
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)
Wish
1. Wish somebody something, but hope somebody do something.
For example:
I wish you an easy test.
I hope you get perfect results in your mathematical test.
2. Wish + Past (We regret something. The meaning is present.)
For example:
I wish you didn’t reach critical values. (you reach them)
Mike’s going to overcome all difficulties. I wish I was going too.
Wish + Past Perfect (we regret about something in the past)
For example:
I wish I had simulated this object with the help of a new computer. (I didn’t simulate)
I wish I hadn’t replaced parts in the machine. (I replaced)
3. I wish I could (do something) = I regret that I cannot do it.
For example:
I’m sorry I can’t help you. I wish I could calculate the resistance in this task. (but I can’t)
I wish I could have (done something) = I regret that I could not do it.
For example:
I heard you bought a new computer. I wish I could have gone to look at it. (but I couldn’t go)
4. I wish (somebody) would (do something)
(we would like something to happen)
For example:
I wish my computer would outstrip my friends’ ones.
I wish somebody would help me to measure current in my laboratory work.
