Examples
-
One was a particular kind of bipolar transistor, called a Schottky bipolar, that was different from what was being used then.
-
Optimal operation of server power supplies with a higher input voltage range of 90V - 305V requires power components such as Schottky diodes that have an extended maximum blocking voltage of 650V.
-
With its multiple conducting tips similar to those of an AFM, the new zig-zag electrode serves as a Schottky barrier to hundreds or thousands of wires simultaneously, harvesting energy from the nanowire arrays.

-
Made of platinum-coated silicon, the tip served as a Schottky barrier, helping accumulate and preserve the electrical charge as the nanowire flexed – and ensuring that the current flowed in one direction.

-
Our interest here is that a Schottky barrier is also critical to the _photophysics_ of semiconductors.
-
A Schottky barrier is set up automatically at the wetted surface of a semiconductor.
-
The result is a region around that boundary -- a "Schottky barrier" -- that has permanent electric charge due to the shifted electrons, the "space charge region."
-
Schottky barriers are _extremely_ important technologically.
-
There, a Dr. Poganski gave a beautiful demonstration that the selenium rectifier was not a Schottky barrier, but a p-n junction between p-type selenium and n-type CdSe, a true heterojunction - although that term did not exist yet.
