'typically 300mv' conflicts with 'Schottky diodes have a drop of only about 0.2 volts.' in opening paragraph.

Fixed.--Heron 19:26, 21 Jun 2005 (UTC)

This article needs expanding with more detail and facts on metal-semiconductor contacts. Any takers?? Al

Schottky Resistance

Whilst the diode does require lowered voltage this in turn means a reduction is temperature and so an increase in later resistance

Spelling

Is it Schottky or Shottky? There is the Walter Shottky institute in Germany. Can anyone verify his real spelling? —The preceding unsigned comment was added by 65.209.67.191 (talk) 20:51, 13 February 2007 (UTC).[reply]

S. M. Sze (Physics of semiconductor devices, ISBN 0471056618 ) mentions the "Schottky effect", and B. Jayant Baliga (Power Semiconductor Decices ISBN 0534940986 ) has a section on "Schottky Barrier Rectifiers". CyrilB 21:32, 13 February 2007 (UTC)[reply]

Pronounciation

-how do you pronounce 'schottky'?

- SHOT-key - RC Cola 20:35, 29 May 2006 (UTC)[reply]

ch !=> h; k !=> k. It's Skotecy. -lysdexia 02:14, 4 October 2006 (UTC)

IMHO you're wrong; I speak German and SHOT-key seems to be right. sch [ger] = ʃ [ IPA ] = sh [eng]; k is pronounced similarly in both languages. Torzsmokus 16:39, 27 January 2007 (UTC)[reply]

Should mention Silicon Carbide devices?

Cree Inc. makes SiC schottky diodes with high Vr ratings. Specs for CSD20120 are: Vr 1200V, If(avg) 20A, Vf(typ) 1.6V @ 10A. CSD20120 Datasheet (PDF). —Ryan 23:45, 29 June 2006 (UTC)[reply]

Yes, it should be introduced alongside of the limitations of Si schottkies (low temp and low voltage). CyrilB 07:49, 30 June 2006 (UTC)[reply]

Schottky diode speed

It should be corrected that microwave mixers are commonly constructed using silicon schottky diodes for operation past 65 GHz. GaAs schottky diode mixers can be used well into the millimeter wave part of the spectrum...the wiki article indicates only to 5 GHz.

There are a few applications "just a little" beyond either 5 or even 65Ghz

http://www.simics.tec.ufl.edu/papers/sankaran3.pdf -- a schottky with an estimated cutoff of 400Ghz

http://trs-new.jpl.nasa.gov/dspace/handle/2014/8909 -- a schottky diode used within a device at the 1400-1900 Ghz range

http://cat.inist.fr/?aModele=afficheN&cpsidt=3433020 -- a reciever operating in the 250Ghz range

Applications

Why are there two applications sections? Nano Dan (talk) 20:54, 12 July 2008 (UTC)[reply]

I combined them into one, but the content needs to be re-written to be more coherent and with less repeating.. probably expanded too... Nano Dan (talk) 00:37, 17 July 2008 (UTC)[reply]

Graph

What about a V/I graph? I find those very useful. 151.61.26.186 (talk) 16:21, 17 March 2009 (UTC)[reply]

Wrong physics

The article now says "When current flows through a diode, it has some internal resistance to that current flow, which causes a small voltage drop across the diode terminals. A normal diode has between 0.7-1.7 volt drops...." Resistance doesn't correspond to a voltage drop without a specified current, so this must be wrong. I'm removing the wrong part, but something informative should be inserted 71.141.88.244 (talk) 23:52, 23 April 2009 (UTC)[reply]

I think this sentence is using the word "resistance" in the colloquial sense. I like the edit though. --Steve (talk) 23:56, 23 April 2009 (UTC)[reply]

Disaster zone

Too many editors who are not competant or experts. Needs a major clean up and re-org. It is such a fundemental component, deserves better. I really really do not like mention of commercial companies in the body of the article. A reference should be made to a published scientific article, not a commercial brochure or a copany web site. I will come back when have a chance. —Preceding unsigned comment added by 12.229.112.98 (talk) 22:10, 19 February 2010 (UTC)[reply]

Agreed. Schottky barriers are damn cool things. If you read this article and the Schottky barrier article, you get the impression that the M/S junction just has some kind of rectifying feature with low voltage drop. This completely ignores the fact that way the Schottky barrier works, and the source of it's useful features, is quantum tunneling; hence the lower voltage drop (tunneled particles maintain kinetic energy; what voltage drop does occur is due to the reflection of some the particles at the potential barrier, and the redistribution of what charges make it through the M/S junction ). Although the Schottky barrier height is poorly understood, The Schottky Diode is an absolutely excellent example of how quantum physics' effects in the macro world, and how we can use even the stranger features quantum mechanics in many pieces of modern technology.

This article needs a rewrite by a physicist, not an electrical engineer.
