are holes protons??

Answer 1

Not exactly, but close. A hole is the absence of an electron, just like a hole in the ground is the absence of dirt. Since it's mobile, I guess a better description would be a bubble. That is, you remove an electron and it leaves a positive charge imbalance behind, which is mobile like a bubble. As neighboring electrons jump in to take its place the charge deficit "jumps" from atom to atom in the opposite direction.

Technically, of course, it's the charge of the nucleus that creates the imbalance, and the nuclear charge is due to protons. But the since the hole moves while the protons stay put, you can't really say the hole "is" a proton.

Answer 2

If you're talking about semiconductor physics, "holes" are more like positrons (the antiparticle of an electron).

In semiconductors with p-type doping (addition of trace elements that suck up electrons), the regular electron bands get depleted. This can be modeled as if there were "holes" (missing electrons) in the electron bands. For the purposes of many calculations, the holes can be treated as if they were real particles themselves. In that case, those particles look like anti-electrons: they have the mass of an electron, but act as if they had positive charge.

Yes.
