Hello Every body!

As shown in below, If i join a heavily doped n+ semiconductor with an ordinary n-type semiconductor,

Three energy band diagrams: n+-type with E_C, E_F near E_C and E_V; n-type with E_C, a dashed E_Fn lower, and E_V; and a joined n+ and n junction with E_C, dashed E_Fn, and E_V, bands bending at the interface.

What is the type of contact that forms between n+and n-type semiconductors ?
is it Ohmic contact or rectifying contact ??
