The answer is "maybe" and you will not know which one to adjust, if any, without a circuit diagram. Just record their positions so you can undo any changes you make, and experiment. As you said - it's cheap.

1) If the n and p doped regions are externally connected using a perfectly conducting wire, why will not any current flow? In thermal equilibrium no current can flow if one connects the two sides of the junction using a perfectly conducting wire. The built-in potential existing at the junction will remain the same, drift and diffusion currents will ...

It's called a diode because the device has two terminals. Devices that have three terminals are called triodes, and those with five pentodes. Words of that type have fallen by the wayside except in the realm of vacuum tube electronics ... except for the word diode, which has hung on. Note that the Wikipedia article that you cite refers specifically to ...

An RTD is a special type of TD, and a double barrier is just one of many possible implementations of resonant tunneling. An RTD is called "resonant" because (under certain conditions) the transmission function is equal to one, i.e. complete transmission. This happens due to wave-like interference between the two barriers. Hence called "resonant": the phase ...

The negative differential resistance creates a special phenomena: under a certain bias and certain incident electron energies, the transmission function through the double barrier is nearly zero. In other words, for a finite voltage domain, the current is nearly zero, i.e. a rectifying behaviour. This can be referred to as "generalized diode", since the ...
