Synthesis, Structure, and Properties of CuBiSeCl 2: A Chalcohalide Material with Low Thermal Conductivity. CHEMISTRY OF MATERIALS : A PUBLICATION OF THE AMERICAN CHEMICAL SOCIETY 2024; 36:4530-4541. [PMID: 38764755 PMCID: PMC11099918 DOI: 10.1021/acs.chemmater.4c00188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 04/04/2024] [Accepted: 04/05/2024] [Indexed: 05/21/2024]
Abstract
Mixed anion halide-chalcogenide materials have recently attracted attention for a variety of applications, owing to their desirable optoelectronic properties. We report the synthesis of a previously unreported mixed-metal chalcohalide material, CuBiSeCl2 (Pnma), accessed through a simple, low-temperature solid-state route. The physical structure is characterized through single-crystal X-ray diffraction and reveals significant Cu displacement within the CuSe2Cl4 octahedra. The electronic structure of CuBiSeCl2 is investigated computationally, which indicates highly anisotropic charge carrier effective masses, and by experimental verification using X-ray photoelectron spectroscopy, which reveals a valence band dominated by Cu orbitals. The band gap is measured to be 1.33(2) eV, a suitable value for solar absorption applications. The electronic and thermal properties, including resistivity, Seebeck coefficient, thermal conductivity, and heat capacity, are also measured, and it is found that CuBiSeCl2 exhibits a low room temperature thermal conductivity of 0.27(4) W K-1 m-1, realized through modifications to the phonon landscape through increased bonding anisotropy.

Abstract
Abstract
Two new copper bismuth sulfide halides, CuBi2S3Cl and CuBi2S3Br, were synthesized by a two-step process of ball milling followed by annealing. Both compounds are obtained as dark grey powders and crystallize in the monoclinic space group C2/m with lattice parameters a = 12.9458(11) Å, b = 3.9845(3) Å, c = 9.1024(8) Å and β = 91.150(3)° for the sulfide chloride and a = 13.3498(8) Å, b = 4.1092(2) Å, c = 9.4173(6) Å and β = 90.322(4)° for the sulfide bromide. Also known for related compounds, the copper atoms are strongly disordered. Quantum-chemical calculations suggest that modelling the structure with fixed copper positions does not satisfactorily describe all structural features, which insinuates copper ion mobility at elevated temperatures.
