thanks for answer ,steve ,according to you i should used rectifier circuit with capactor,but what i am thinking to do is to detect THz waves via antenna and schotkkey diode then i need a dc out pad to move this detected signal to LNA (low noise amplifier),my problem is that i am not understanding how take out signal detected by len and diode.i read a paper regarding it and they have used dc out pad for this but i have no idea what does it mean by dc out padOK, we've all been kidding you about needing extra information.
Just get a 1N5404 and connect it to a capacitor of about 2.64mF/1000V. Be careful, terrahertz radiation is powerful and you could get a powerful shock which might collapse your Schrodinger equation.
well steve yes its my first work on circuit design and may be i am wrong in selection of a forum to get some guidance because i consider it a serious forum instead of making fun of other's problem firstly,and attachment of paper and refernce with this post was an option if i get a bit good response from any serious member.also one more thing terahertz waves can damage you schrodinger eq etc was terrible joke at all.Your response to my joke indicates that you have no idea of the issues involved in doing this.
In addition to that you refuse (or are unable) to provide more details (even a link to the paper you refer to).
I recommend you re-read post #2 and #3 in this thread.
davespecifically where in the Terahertz range ?
at that freq you are well into the infrared spectrum, so you should be looking at IR photo-transistors/diodes as are used in everyday IR remote control receivers in TV, VCR, DVD's etc

yes this paper is what i want to make on same grounds but with different requirements,yes i have facility to fabricate chip. you said "very first image tells you how to make a detector."how???i dont get the point???If you did, then the very first image tells you how to make a detector.
It gives you a rough idea of the chip you need to fabricate.
Do you have the facilities to fabricate chips?
in fabrication again my problem is after fabricating schottkey diode and adding it in middle of antenna with glue how to take signal out by diode??they have made signal out pad on antenna arms which is new for me???signal output pad or dc pads are ??????and how to mount them on antenna??this is my problem in fabrication and even is simulationI would read section II entitled "Fabrication".
The signal-out pad is a die scale wire bond pad. Attempting to replicate the Japanese team's methods without a wafer fab foundry and die scale assembly facilities would likely be a fruitless endeavor.
I'm finding it difficult to believe you have such facilities and fail to recognize a bond pad in the paper's micrograph. Perhaps it's just a language translation issue. Are you using Google translate from Bulgarian?
thanks a lot for this post,i dont know about it as i have been working on antenna designing and characterization and now got a project like this that involve chip fab etc so on simulation ground i can do but for to understand on fab ground was very difficult.thanks for help i got ideaThe signal-out pad is a die scale wire bond pad.
