Au/Ra Au/Ra Jamie Lou Stenzel (born 15 May 2002), known by her stage name as Au/Ra, is a pop singer-songwriter, who collaborated with CamelPhat in the 2018 single "Panic Room", and was featured in Norwegian DJ Alan Walker's number-one single "Darkside" in the same year. Au/Ra was born in Ibiza, but was since raised in St. John's, Antigua by a musical family—her father being the German producer Torsten Stenzel. Her stage name Au/Ra consists of two elements from the periodic table: Au stands for gold, a transition metal with the atomic number 79, while Ra stands for radium, an alkaline earth
Chemical potential function, Fermi energy, and Fermi level. For example, n-type silicon has a higher internal chemical potential of electrons than p-type silicon. In a p–n junction diode at equilibrium the chemical potential ("internal" chemical potential) varies from the p-type to the n-type side, while the total chemical potential (electrochemical potential, or, Fermi level) is constant throughout the diode. As described above, when describing chemical potential, one has to say "relative to what". In the case of electrons in semiconductors, internal chemical potential is often specified relative to some convenient point in the band structure, e.g., to the bottom of the conduction
