Low-temperature thermal conductivity of the metal-organic perovskite [C(NH$_2$)$_3$][Cu(HCOO)$_3$]

ORAL

Abstract

We report measurements of thermal conductivity on single crystals of the metal-organic hybrid perovskite [C(NH$_2$)$_3$][Cu(HCOO)$_3$] in the temperature range 5K to 300K. In addition to its potential in photovoltaic applications, this compound draws interest for its low-dimensional antiferromagnetism associated with Cu-formate chains (along the crystallographic $c$-axis of the orthorhombic structure).$^a$ We will present thermal conductivity measurements along the three main symmetry directions ([100], [010], and [001]) and discuss its anisotropy. \vskip .1in \noindent $^a$ Hu {\it et al.}, Chem.
