Yes so why are you saying the opposite ?

Yes so why (are you: NO !) the autodesk article saying the opposite ? 

On a physical diode, you'll notice two terminals extending from a tin can shape in the middle. One side is the positive terminal, called the anode. The other terminal is the negative end, called the cathode. Going back to our flow of electricity, current can only move in a diode from the anode to the cathode, never the other way around.

Storage polarization is intellectual bull shit !

what it means is where the free electron has been leaves a hole
your talking about where they have been going the other way !

So if your walking forward where you have been is the past where you have been walking backwards !

a great philosophy your into !

[lancaIV]

At first : if philosophy works then this philosophy is right !


Seconds : there is the "ordinary" anode-cathode diode,definded, and the more specific diodes kinds !

When You look for the diode as n-p-n or p-n-p structure Ýou get solar or photo-electric cells or with wider emf bandgap thermovoltaic cells !

But here You need to define the spectrum between diode and transistor and function  :

in memoriam Gustav Pese I recommend in his "Show postes" Nr. 27 : the simple circuit
and
for later experiments www.phils.com.au/kron.htm related " negative resistor" !
Between Peses postes Nr.1-27 is something,more redundant,as overview, about the in-/out-put effect to read.
Non hertzian wave energy (searchmachine : cold energy )

About LEDs and their functionality related official 100 000 hours work duration and real life experience a professional ex-Phillips engineer told me that the resistors connection is the problem !

Related 'non hertzan wave' and the autodesk-article 1diode and 4 diodes circuit scheme ,wth ONLY positive voltage output,the inverse way : ONLY negative voltage delivered as ambiental energy converter by sympathetic resonance !

Between 0° C and 0° K are 273 pressure/force degrees energy !

One the way to monopolar attraction or monopolar repulsion : radar/stealth !

When quoting other peoples so called statements as actual facts and when one hasn't bothered to proved or tested ones self could be misleading to others or as missing modern descriptive key words or plain wrong.
This practice can often lead to a waste of material or damage to expensive components going up in smoke if replicated!

Lets for instance look at the positive and negative temperature 'coefficient' terminology

Both of these type of devices were used early on to demagnetise the old shadow mask tube as it's 'mask'
was made of a ferrous magnetic material, I would suggest if your going to use 'quotes' by others you should use an up to date terminology and thus prove or show with a diagram how it works.

Also results I found for negative resistance coefficient.
A negative coefficient for a material means that its resistance decreases with an increase in temperature.

Semiconductor materials (carbon, silicon, germanium) typically have negative temperature coefficients of resistance.
