House - Simple English Wikipedia, the free encyclopedia
A house is a building that is made for people to live in. It is a "permanent" building that is meant to stay standing. It is not easily packed up and carried away like a tent, or moved like a caravan. If people live in the same house for more than a short stay, then they call it their "home". Being without a home is called homelessness. Houses

Semiconductor Doping - an overview | ScienceDirect Topics
The quality of the ohmic contact is frequently described in terms of contact resistance, R s (Ω·mm), or specific contact resistivity, P s (Ω·cm −2).However, since these properties depend heavily on the semiconductor doping level, these parameters are not to be defined as fundamental metal-semiconductor interface, as the Φ B n,0 is to a Schottky junction.
