SUMMARY

The discussion confirms that when a heavily doped n+ semiconductor is joined with an ordinary n-type semiconductor, an Ohmic contact is formed. This conclusion is based on the principles of semiconductor physics, where the high doping level of the n+ material allows for efficient charge carrier movement across the junction. The participants agree that this type of contact facilitates low-resistance electrical connections, essential for various electronic applications.

Hello Every body!

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

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