How is the Electric Field Established Inside a Diode When Voltage is Applied?

Hello,

When a Voltage is applied to a diode, how the electric field is established inside the diode? Is it the same as a resistor which surface charges density establish electric field inside it?

Thanks

Resistors are not semiconductors and do not attract the charge carriers to their opposite polarity pole.

Ignoring variable magnetic field it is established as E = -grad V
