holey

adj : allowing passage in and out; "our unfenced and largely

unpoliced border inevitably has been very porous" [syn:

{porous}]

hole

The absence of an {electron} in a

{semiconductor} material. In the {electron model}, a hole can

be thought of as an incomplete outer electron shell in a

doping substance. Holes can also be thought of as positive

charge carriers; while this is in a sense a fiction, it is a

useful abstraction.
