Advances in Thermoelectric Cu2ZnSnS4: From Structure, Synthesis to Performance

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Thermoelectric technology has the capacity to directly convert waste heat into electricity and vice versa. For a long time, Cu2ZnSnS4 (CZTS) has been extensively researched in the domains of solar cells and photocatalysis due to its exceptional photovoltaic properties, but its wide bandgap prevents it from being favored in thermoelectrics ...

Effect of temperature gradient on microstructure and properties of GaSb crystals grown with Bridgman method

open access: yesMaterials Research Express, 2020
GaSb crystal ingots were grown with vertical Bridgman method. The effects of temperature gradient on the structure and properties of GaSb crystals were investigated. When the temperature gradient increased from 5 to 7 °C cm ^−1 , the crystallinity of the

Market regulation and productivity: The case of the Canadian Wheat Board

open access: yesAmerican Journal of Agricultural Economics, Volume 108, Issue 4, Page 1193-1218, August 2026.
Abstract Changes to regulatory environments influence firm‐level incentives, which can move the productivity frontier or reposition firms within an existing frontier. Estimating causal effects of policy changes requires a credible counterfactual for productivity in the absence of policy change.

Mathematical Modeling of Binary Alloy Solidification

open access: yesActa Polytechnica, 2000
Te is simulated. Moving boundary conditions for temperatures are taken into account, which makes it possible to simulate the Bridgman method of crystal growth for instance.

Thermal Field Simulation and Optimization of PbF2 Single Crystal Growth by the Bridgman Method

open access: yesCrystals
PbF2 single crystals are usually grown in the temperature gradient region by the Bridgman–Stockbarger method. Temperature distribution during the growth process is particularly important for the preparation of high-quality crystals.

Impurity diffusion in the melt in crystal production by bridgman's method [PDF]

open access: yesJournal of engineering physics, 1971
An approximate solution is derived for the one-dimensional diffusion of impurities in a melt in directional crystallization within a restricted volume and motion of the interface and constant speed. Results are given for the position of the diffusion layer and the impurity concentration.
