Talk:Indium gallium nitride

445nm InGaN Diodes
Woo boy, I'm loving my new 445nm Laser. Thanks InGaN! 71.84.126.174 (talk) 11:00, 18 October 2010 (UTC)

What bandgap as function of x
It says the bandgap can be tuned by varying x in the formula but doesn't show the graph or even any typical values (eg when used in LEDs) eg. the x=0.02 and 0.3 mentioned as 'usual' limits. - Rod57 (talk) 16:51, 29 October 2016 (UTC)

What x, bandgap and voltage drop when used for various colour LEDs
Light-emitting_diode says InGaN can be used for green, blue, violet and UV LEDs but that article and this article do not say what x is used to generate each colour LED, or what the corresponding voltage drops would be. - Rod57 (talk) 17:01, 29 October 2016 (UTC)
 * Old comment, but what is tuned is the amount of indium versus the amount of gallium. By varying the ratio between the two, you can change the bandgap.  M r A urelius R   Talk! 23:43, 16 September 2020 (UTC)
