Calculation of the superconducting transition temperature in niobium

Self-Consistent Calculation of the q Dependence of the Electron-Phonon Coupling in Aluminum

“…To calculate X we use the expression introduced by Allen 22 and used by others 23,24 to evaluate this parameter,…”

First-principles study of phonons and superconductivity of Nb1−xMoxwithin the virtual-crystal approximation

“…The Nb 1−x Mo x alloy has been investigated extensively in the past because of its superconducting properties. In particular, the observation of the non-monotonic behavior of the superconducting critical temperature (T c ) as a function of Mo-content, x, has initiated numerous experimental and theoretical studies of its structural [1][2][3][4][5], electronic [6][7][8][9][10][11][12], vibrational [13][14][15][16][17][18][19][20][21], and superconducting properties [21][22][23][24][25][26][27][28][29][30][31]. While Nb possesses the highest T c among elemental metals (9.25 K), T c decreases with increasing Mo-content, falling below 0.5 K for 0.4 x 0.9 and slightly recovering again to T c = 0.92 K at x = 1 (Mo) [1,22,32].…”
