Title: Nodeless Superconducting Gap in the Candidate Topological Superconductor Sn{sub 1-x}In{sub x}Te for x=0.7.

Abstract

High-pressure synthesis techniques have allowed for the growth of Sn1-xInxTe samples beyond the ambient In-saturation limit of x = 0.5 (T-c similar to 4.5 K). In this study we present measurements of the temperature dependence of the London penetration depth Delta lambda(T) in this superconducting doped topological insulator for x = 0.7, where T-c(,onset) approximate to 5 K. The results indicate fully gapped BCS-like behavior, ruling out odd-parity A(2u), pairing; however, odd-parity A(1u) in pairing is still possible. Critical field values measured below 1 K and other superconducting parameters are also presented.

Doping-evolution of the superconducting gap in single crystals of (Ca _1-x La _x ) ₁₀ (Pt ₃ As ₈ )(Fe ₂ As ₂ ) ₅ superconductor from London penetration depth measurements

Journal Article Cho, K. ; Tanatar, M. A. ; Ni, N. ; ... - Superconductor Science and Technology

The doping-evolution of the superconducting gap structure in iron-based superconductor (Ca ^{1-xLa_x)₁₀(Pt₃As₈)(Fe₂As₂)₅(x = 0.04, 0.06, 0.09, 0.11, and 0.18) was probed by high-resolution measurements of the London penetration depth, λ(T). The samples spanned compositions from underdoped to slightly overdoped with superconducting critical temperatures, T_c, from 12.7 K (x = 0.04) through (optimal) 23.3 K (x = 0.11) to 21.9 K (x = 0.18). The low-temperature variation (up to 0.3 T_c ) of λ(T) was analysed using a power-law function, Δλ = AT_n. For compositions close to the optimal doping, (x = 0.09, 0.11, and 0.18), characterized by T_c > 20K,more » Δλ(T) shows a tendency to saturation, indicative of a full gap on the Fermi surface. Fitting over the lowest temperature range (T < 0.1 T_c) gives n = 2.6. This value is well outside the range 1 ≤ n ≤ 2 expected for the line-nodal superconductor. The exponent n decreased to n ~ 2 in the two most underdoped compositions x = 0.04 (T_c = 12.7 K) and 0.06 (T_c = 18.2 K), implying the development of a notable gap anisotropy revealed by the enhanced influence of pair-breaking scattering. This decrease is accompanied by a significant increase of the total variation of the penetration depth Δλ in a fixed temperature interval (e.g., T_min - 0.3T_c). Both the decrease of the exponent and the increase of the absolute value of Δλ in the underdoped regime are similar to the observations in other charge-doped iron-based superconductors, such as doped BaFe₂As₂ and NaFeAs, suggesting a universal behavior in iron-based superconductors.}« less

Unusual phonon density of states and response to the superconducting transition in the In-doped topological crystalline insulator ${Pb}_{0.5} {Sn}_{0.5} Te$

Journal Article Ran, Kejing ; Zhong, Ruidan ; Chen, Tong ; ... - Physical Review B

Here, we present inelastic neutron scattering results of phonons in (Pb _0.5Sn _0.5) _1–xIn _xTe powders, with x = 0, and 0.3.The x = 0 sample is a topological crystalline insulator, and the x = 0 . 3 sample is a superconductor with a bulk superconducting transition temperature T _c of 4.7 K. In both samples, we observe unexpected van Hove singularities in the phonon density of states at energies of 1– 2.5 meV, suggestive of local modes. On cooling the superconducting sample through T _c, there is an enhancement of these features for energies below twice the superconducting-gap energy.more »« less
