AB  - We report discovery of KFe1.05Ag0.88Te2 single crystals with semiconducting spin glass ground state. Composition and structure analyses suggest nearly stoichiometric I4/mmm space group but allow for the existence of vacancies, absent in long-range semiconducting antiferromagnet KFe0.85Ag1.15Te2. The subtle change in stoichometry in Fe-Ag sublattice changes magnetic ground state but not conductivity, giving further insight into the semiconducting gap mechanism.
