What Are the Best Resources to Understand Resonant Tunneling Diodes?

[CMJ96]

Hi guys for my group project this year my team needs to apply two computational methods to a real system.
The two methods are transfer matrix and finite difference and we have chosen to apply them to a resonant tunnelling diode.
Can any of you guys recommend any resources which may be useful to help write about the theory behind a resonant tunnelling diode?
Thanks for any help in advance
