摘要：
The single crystal of ThCr2Si2-type BaPd2As2 was successfully prepared by a self-flux method, and the crystal structure was characterized by X-ray diffraction method with the lattice parameters a = 4.489(2) angstrom and c = 10.322(3) angstrom (space group I4/mmm, No. 139). Bulk super-conductivity below a T-c (critical temperature) of 3.85K was revealed in this compound by the measurements of resistivity, magnetic susceptibility and specific heat, and this T-c is much higher than those of other isostructural Pd-based superconductors.
