Description
Jingxiang Cheng and eight colleagues dope a lanthanum oxychloride crystal to make chloride ions move faster through it, in a study from twenty twenty-six. Design rules for solid halide conductors remain poorly defined. Halide carriers matter for batteries and electrochemical computing. Substituting other metals at one crystal site was their strategy.
Magnesium, calcium, and strontium swaps created charge-balancing chloride vacancies. The crystal structure survived the substitutions. Light-emission probes revealed vacancy-related electronic states. Calcium alloying boosted conductivity by three to four orders of magnitude. Strontium and magnesium helped less. Heat measurements showed the calcium and strontium versions had softer lattices. A compliant lattice deforms to let chloride ions pass. The work names site-selective doping as a design lever.
