What is Schottky Diodes?
Schottky diodes have a low forward voltage drop, making them ideal for use in high-efficiency power converters
A diode is a two-terminal device that acts as a one-way switch. The Schottky diode, also known as a metal-semiconductor diode, is a discrete semiconductor that can withstand high input resistance voltage with the semiconductor acting as a cathode and the anode.
Walter H. Schottky, a German physicist, inspired the naming of the diode. It is also known as a surface barrier diode, a hot-carrier diode, a majority carrier diode, a hot-electron diode, and a Schottky barrier diode. A Schottky diode’s low forward voltage ranges from 150 mV to 450 mV, its most notable characteristic. The Schottky diode is a highly high-speed switching device because of its low forward voltage.

Building a Schottky diode
A Schottky diode is a type of semiconductor device that uses a metal-semiconductor junction to create a rectifying junction. The metal-semiconductor junction allows for a very low forward voltage drop, which makes it ideal for use in high-efficiency power converters and switching regulators. The construction of a Schottky diode requires n-type and p-type semiconductor materials and metal contact.
A Schottky diode is a type of semiconductor diode that utilizes a metal-semiconductor junction to achieve a low forward voltage drop. This makes it an ideal choice for high-frequency and switching applications. The construction of a Schottky diode typically involves depositing a thin layer of metal onto a semiconductor substrate.
A Schottky diode is a semiconductor device that uses a metal-semiconductor junction to form a diode. The metal-semiconductor junction creates a very low resistance path for current to flow, making the Schottky diode ideal for use as a rectifier in power supplies and other electronic circuits. Schottky diodes are also used as voltage regulators in power supplies and as switches in high-speed digital circuits.

VI characteristics of Schottky diode
The Schottky diode has a fast switching speed- making it ideal for use in electronic circuits.
In the reverse bias region, it can be seen that a Schottky diode conducts a much higher reverse saturation current. The reverse current in a Schottky diode is not due to minority charge carriers; instead, it only contributes to electron current. Again, it can be noticed that the reverse breakdown voltage of the Schottky diode is smaller than the PN junction diode.
The energy needed to separate an electron from an ion varies depending on whether the material is an n-type semiconductor or a metal. Compared to free electrons in a metal, electrons in n-type semiconductors have higher potential energy. The Schottky barrier height, which prevents any transfer of electrons from the semiconductor to the metal, is equal to the difference between the work functions of metal and semiconductor. The Schottky diode does not have a P-type semiconductor, hence holes are not the dominant charge carriers.
