☑ Silicon Mim Diode

Mim means you can put diodes in regions of your chip where they couldnt practically be fabricated before without a lot of time doing a one off chip in a lab. Connected to a metaldouble insulatormetal miim diode see figure 3.

The application of mim diodes to solar energy conversion is investigated.

Silicon mim diode. Mim diodes made from the native oxides of chromium aluminum and niobium are experimentally fabricated. The same concept applies to electrons in mim diodes. The chief difference between germanium and silicon diodes is the voltage at which electric current begins to flow freely across the diode.

For silicon diodes the built in potential is approximately 07 v 03 v for germanium and 02 v for schottky. Depending on the geometry and the material used for fabrication the operation mechanisms are governed either by quantum tunnelling or thermal activation. Well also learn how to analyze circuits that contain more than one ideal diode in conjunction with resistors and dc power sources.

Characteristics of the ideal silicon diode may 06 2016 by donald krambeck in this article we will discuss some characteristics of the ideal diode. Metal insulator metal mim diode is a type of nonlinear device very similar to a semiconductor diode that is capable of very fast operation. Doctor of philosophy in electrical engineering.

The two poles of the antenna overlap to form the miim sandwich. Of the requirements for the degree of. A dissertation submitted in partial fulfillment.

Silicon diodes require more voltage to conduct current. A germanium diode typically begins to conduct electric current when voltage properly applied across the diode reaches 03 volts. In doing that a part of the electron beam passes through the barrier but another part reflects back.

The diode is commonly said to have a forward threshold voltage above which it conducts and below which conduction stops. With a lot often being several months to a year assuming everything turns out perfectly assuming your lab even has all the necessary equipment and assuming you dont have something better to do which is rare if youre not still a grad student. Department of electrical engineering.

The antenna is sized on the order of a wavelength roughly a millimeter for terahertz radiation and one micron for near infrared wavelengths. In the 2000s there was an attempt to use thin lm mim diodes in the infrared energy harvesting area 7. And frequency selective thermal emitters for solar energy harvesting and detection devices.

Design fabrication and characterization of mim diodes. Point contact diodes this diode structure provides improved device reproducibility and durability. When the electron reaches the barrier the insulator in between the metal strips it absorbs energy from the surroundings in order to pass through the insulator.

Metal insulator metal mim diodes are used to rectify high frequency electromagnetic radiation coupled to them via an integrated antenna. Mim tunneling diodes have found application in rectication mixing and harmonic generation at infrared frequencies 16. Thus if an external voltage greater than and opposite to the built in voltage is applied a current will flow and the diode is said to be turned on as it has been given an external forward bias.

It takes 07 volts to create a forward bias situation in a silicon diode.
