Whereas most metals are good electrical conductors,
 and most nonmetals are poor electrical conductors,
 metalloids are somewhere in-between; electrical semiconductors,

Some current can flow through a semiconductor if the potential difference across the sample is high enough. But significant resistance will be experienced.
