InSb is a promising mid-temperature thermoelectric material, and its n-type properties have been widely studied. For device applications, it necessary to p-type counterparts. Here, we report the realization of with enhanced performance via Cd doping. A high-power factor 1.91 × 10−3 W m−1 K−2 obtained in In0.93Cd0.07Sb at 723 K due increased carrier concentration. Moreover, lattice thermal conductivity decreased 2.0 K−1 owing significant multiscale phonon scattering suppressed bipolar...
Catering to the general trend of artificial intelligence development, simulating humans' learning and thinking behavior has become research focus.
Bi(Te, Se)-based compounds have attracted lots of attention for nearly two centuries as one the most successful commercial thermoelectric (TE) materials due to their high performance at near room temperature. Compared with 3D bulks, 2D thin films are more compatible modern semiconductor technology and unique advantages in construction micro- nano-devices. For device applications, average TE over entire operating temperature range is critical. Herein, highly c-axis-oriented N-type Se)...
Incorporating nano-dispersions into thermoelectric (TE) materials is an effective approach to enhance the TE properties. Herein, performance of Cu2Se thin film significantly enhanced by incorporating highly dispersed SnSe nano-inclusions. The high power factor (PF, ∼11.0 μW cm−1 K−2, 310 K) at near room temperature achieved mainly due energy filtering effect that originated from potential barrier difference. total thermal conductivity decreased owing simultaneously reduced electrical and...
Significant enhancement of light-induced transverse thermoelectric (LITT) effect in tilted BiCuSeO film has been achieved via introduction an ultra-thin layer gold nanoparticles (AuNPs) with the thickness a few nanometers. In both cases pulsed and continuous light irradiation, about two times increment LITT voltage sensitivity is observed for coated 4-nm-thick AuNPs layer. This can be ascribed to increased photo-thermal conversion efficiency owing efficient usage incident Thicker will...
Abstract Food grade (K 2 CO 3 wt.%>99.0%, GB/T 25588-2010) potassium carbonate ) has been extracted from low concentration [K + ] solutions of K -Na -H O, which refers to a subsystem brine water in the Lop Nor Lake West China. Procedures isothermal evaporation, crystallization, acidification, filtration, and calcination were employed prepare . This research focuses on phase study metastable equilibria between O KHCO -NaHCO O. The solubility, density, conductivity, pH values determined....
Abstract It is of importance to reclaim single-salt potash from Li + -type brines low concentration. In this work the potassium salts KHCO 3 was efficiently separated lithium carbonate-type with aid CO 2 carbonation. The phase field provided in which precipitation occurs and can be obtained. concentration [Li ] also successfully concentrated a high level (8.1 g/L), used as sources for -salts production using pre-developed strategies, looks forward wider applications resources natural brine....
It is of great importance to separate potassium salts from carbonate-based lakes, especially the low-[K+] but high-[Na+] brine which has been discovered around world. Here phase diagram quaternary system Na+, K+//Cl–, CO32––H2O was experimentally studied at 298.15 K via method isothermal evaporation, and results corrected previous reported by Blasdale (J. Am. Chem. Soc. 1923, 45, 2935–2946). The type appeared their solubility during density vs composition pH values were plotted based on...
