Product Overview

 

Thermoelectric materials are functional materials that can convert thermal and electrical energy by utilizing their internal charge carriers and phonons. The effective operation of thermoelectric materials is mainly based on three physical effects, namely the Seebeck Effect (discovered in 1794, referring to the phenomenon of thermal to electrical conversion between two different conductors), the Peltier Effect (discovered in 1834, the phenomenon of electrical to thermal conversion between two different conductors), and the Thomson Effect (discovered in 1851, the phenomenon of heat absorption and release in a single conductor).

The conversion efficiency of thermoelectric materials is determined by the dimensionless parameter - thermoelectric figure of merit ZT, and its calculation formula is:

ZT=σ S2T/k, where σ is the conductivity, S is the Seeback coefficient, which is the inherent electronic transport performance parameter of thermoelectric materials, T is the temperature, and k is the total thermal conductivity. A common method to improve the performance of thermoelectric materials is to introduce multi-scale second phases to regulate the microstructure of thermoelectric materials, thereby changing the band structure and crystal structure of the matrix to coordinate various parameters and optimize their thermoelectric transmission performance.

Traditional inorganic thermoelectric materials are currently a type of thermoelectric material with a wide range of applications and a long research time. Mainly including Mg based thermoelectric materials (Mg2X (X=Si, Sn)), Bi2Te3 based thermoelectric materials, SiGe based thermoelectric materials, PbX (X=S, Se, Te) based thermoelectric materials, SnX (X=S, Se) based thermoelectric materials, GeTe based thermoelectric materials, and oxide based thermoelectric materials.

PbTe based thermoelectric materials are thermoelectric materials in the medium temperature range, exhibiting excellent thermoelectric properties in the temperature range of 300-900K. Its bandgap width is about 0.3 eV, belonging to wide bandgap semiconductors, with a typical NaCl type crystal structure, highly symmetrical crystal structure, and high conductivity. At the same time, its band structure is also relatively complex, and the strong non harmonic vibration caused by local eccentricity of Pb atoms makes PbTe have low thermal conductivity while having a high Seebeck coefficient.

What a disappointment!
Format: Board book
What you see is what you get. You pay all that money just to get a handful of unexciting sounds. What a disappointment!

great book for toddlers
Format: Board book
I was a former Kdg teacher and read this to my kids many times and they alway wanted more. It has undergone a few changes I still the old original one where they can open the box This is one of my favorites for baby showers now
