Can a fundamentally superconducting circuit include semiconduction?
Kholdstare said:What do you mean?
Circuit of separate semiconductor and superconductor devices?
Or, Single device having both properties?
f95toli said:There is no such thing as a semiconducting Josephson junction (or SQUID) since the two electrodes of a JJ have to be superconducting. However, what you can have is a JJ where the barrier between the electrodes is made from a semiconductor.
jsgruszynski said:Basically semiconductors are only "semi-conducting" because they have free carriers that are thermally released to float around the material and conduct currents. Doping can increase this carrier concentration but ultimately all the carrier concentration formulae have an ekT term in them that describes the thermal carrier release from the dopant atoms. As you drop the temperature, this term goes to zero and the semiconductor turns into an insulator electrically. Ergo the term "Freeze Out".
Loren Booda said:It seems that this is what I was looking for. Do you know of any links to illustrations of this? Thanks.
Semiconduction in a superconducting circuit refers to the flow of electrons through a material that is neither a perfect conductor nor an insulator. This type of circuit is used in superconducting devices to control the flow of electricity and create unique properties, such as zero resistance.
In a superconducting circuit, semiconduction occurs at a critical temperature where the material transitions from a normal conductor to a superconductor. This means that the electrons can flow without any resistance, unlike in a traditional semiconductor where there is still some resistance.
The most commonly used material for semiconduction in superconducting circuits is silicon, due to its abundance, low cost, and well-understood properties. Other materials, such as germanium and gallium arsenide, are also used for specific applications.
Semiconduction in superconducting circuits is used in a variety of applications, including quantum computers, medical imaging devices, and particle accelerators. It is also being explored for use in high-speed computing and communication technologies.
One of the main advantages of using semiconduction in superconducting circuits is the ability to create devices with zero resistance, which allows for extremely efficient and fast flow of electricity. This also means that there is minimal loss of energy, making superconducting circuits ideal for high-performance and low-power applications.
