Resonance states and hyperconvergence induced by tungsten doping in SnTe: Multiband transport leading to a propitious thermoelectric material

•First report of hyperconvergence in conduction bands by substitutional doping of W in SnTe.•Tungsten doping in SnTe leads to introduction of resonance levels.•W doping results in increase in the band gap and valence band convergence.•Multiple electronic valley generation by W doping in SnTe leads t...
