Ternary chalcogenides of CuFeS2–x (x= 0.00–0.20) chalcopyrites were synthesized via
vacuum melting reaction/uniaxial hot pressing, and their thermoelectrical properties were …

Chalcopyrite (CuFeS2) is a widespread natural mineral, composed of earth‐abundant and
nontoxic elements. It has been considered a promising n‐type material for thermoelectric …

Cu5FeS4, one of the promising Earth-abundant and low-toxicity Cu-based thermoelectric
materials, transforms from an orthorhombic structure to a cubic phase when heated, which …

The dearth of n-type sulfides with thermoelectric performance comparable to that of their p-
type analogues presents a problem in the fabrication of all-sulfide devices. Chalcopyrite …

CuFeS2 (chalcopyrite) is a promising n-type thermoelectric candidate for low-grade waste
heat recovery. In this work, chromium-containing CuFeS2 materials of general formula Cu1 …

Bulk and nanoparticles of n-type CuFeS 2 Chalcopyrite have been synthesized using
vacuum melting reaction and conventional hydrothermal method, respectively. The powder …

An effective strategy to enhance thermoelectric performance consists of scattering phonons
by point defects, such as the ones intrinsic to the n-type isocubanite CuFe2S3. In this …

Composed of inexpensive and naturally abundant elements, the chalcopyrite mineral
CuFeS 2 has received attention as a potentially useful thermoelectric. We use first-principles …

Designing irregular but desirable atomic arrangements in crystal lattices of solids can greatly
change their intrinsic physical properties beyond expectations from common doping and …

CuFeS 2 is an eco-friendly n-type thermoelectric (TE) material but with poor performance. It
is worth noting that the bandgap (E g) reduction can enhance the carrier mobility (μ H) which …
