Silicon superconductor energy storage

Can superconductivity be introduced in cubic silicon?

It is apparent that if superconductivity can be introduced in cubic silicon, that will bring a breakthrough in low-dissipation electronic circuitry. Motivated by this, attempts have been made by several research groups to induce superconductivity in silicon through a number of different routes.

What is superconducting silicon?

In this quest, superconducting silicon can address the challenges owing to the established fabrication of high quality silicon based functional devices. The commonly used Josephson junction assembly for superconducting applications such as qubits is Al/AlO x /Al (or Nb/AlO x /Nb).

Can silicon be used as a superconductor?

Besides the bulk form of silicon, it is different structural forms including silicene and nano-structured silicon have shown potential for superconducting applications with relatively higher transition temperatures.

When was superconductivity discovered in silicon based systems?

In 2006, the discovery of superconductivity in doped cubic phase of silicon by Bustarret et al opened a new era of research on such superconducting transition in doped silicon based systems [ 16 ]. Until this discovery, superconductivity had only been obtained in high-pressure structural phases of silicon.

Are supercapacitors a good energy storage device?

Supercapacitors are electrochemical energy storage devices possessing both great power density and energy density with long lifecycle and high charging/discharging (Sun et al. 2018a). These properties are the reason for high-energy storage ability exhibited by supercapacitors for technological advancement (Chen and Dai 2013).

Does silicon have a superconducting phase?

This may facilitate the appearance of a superconducting phase in the sh phase of silicon. The observation of superconductivity in sh phase of Si was also suggested by Needs and Martin from self-consistent density functional theory [ 30 ].
