i'm looking for exhibits a negative resistance characteristic diode and i can't find it i know that the diac one of them can u give me more names plz ot I-V characteristics for them i would be very happy

Gunn diodes, Tunnel diodes, IMPATT diodes, other special constructs that use multiple quantum wells.
edit to add:
Sorry, the general characteristics of these devices is that they demonstrate the neg resistance at a point called the Vv ( voltage valley) where I goes down as V increases , of course theres a point where I rises again. The plot looks like a sine wave
HEY ENG tanx alot for ur answer but when i looked for the I-v i didn't find eany coz i have to att in my report some link or photo so would u help me :roll:
I got your message. The report I cited has a tunnel diode v-i curve at the top. It is reproduced below. TillEulenspiegel posted a Gunn diode curve for you.
If these aren't what you are looking for, you need to be more specific.
