Is there a material with fairly high resistivity (at least semi-conductor level), but also allows the flow of charge through it (and subsequently to the ground)? The flow of charge does not need to be fast, it can be very slow if necessary. The higher resistivity, the better.

So ideally, if that material is left alone on the ground, its steady-state should have very little charge, and thus have negligible or zero electric field (even if you initially applied some charge to it). Basically, the material is able to be discharged in finite-time, regardless of its fairly high resistivity. 

The speed of discharge is the property I'm particularly interested in, but based on what I've seen, this property might be independent of resistivity.

I am not sure if such properties are documented, so if you know what the property is called, please tell.

Thanks
