Specification Brand : MRUPEZIU BulletPoint1 : ✦Prices in the size catalog are per 100g BulletPoint2 : ✦Semiconductor refrigerator is a transducer, through which electrical energy can be directly converted into heat energy, its role is similar to the refrigerator refrigeration machinery, can achieve the purpose of refrigeration, but in terms of structure and working principle, it is very different from mechanical refrigeration BulletPoint3 : ✦The important characteristic of N-type semiconductors is that after a certain amount of a certain impurity penetrates into the semiconductor, it can not only greatly increase the electrical conductivity, but also manufacture semiconductors of different properties and different uses according to the type and amount of impurities incorporated. When an impurity is incorporated into a semiconductor, free electrons are released, which is called an N-type semiconductor BulletPoint4 : ✦P-type semiconductors use "holes" to conduct electricity. Under the action of external electric field, the "hole" flow direction and the electron flow direction are opposite, that is, the "hole" flows from the positive plate to the negative electrode, which is the P-type semiconductor source BulletPoint5 : ✦Advantages of temperature difference power generation: no noise, simple installation, long life, stable performance BulletPoint6 : ✦Temperature difference cooling components have been widely used in experimental instruments, consumer products and industry BulletPoint7 : ✦100g/Package Color : N Type - Weight=100g ExternallyAssignedProductIdentifier : 9331855811468 ItemForm : Bismuth Telluride Crystal Particle ItemName : Bi2Te3 Electrode, P&N Type Bismuth Telluride Crystal Particle, 100g/set Semiconductor Thermoelectric, Semiconductor Refrigeration Sheet Material (1, N Type - Weight=100g, 1.45 * 1.45 * 1.67mm) ItemPackageDimensions_Height : 4 centimeters ItemPackageDimensions_Length : 22 centimeters ItemPackageDimensions_Width : 9 centimeters ItemShape : Particle ItemTypeKeyword : lab-electrodes Manufacturer : MRUPEZIU Material : Bismuth Telluride Crystal Particle ModelNumber : Cerlyiontz7qfrghcb4 NumberOfItems : 1 PartNumber : Bismuth Telluride Crystal Particle ProductDescription : Semiconductor refrigerator is a transducer, through which electrical energy can be directly converted into heat energy, its role is similar to the refrigerator refrigeration machinery, can achieve the purpose of refrigeration, but in terms of structure and working principle, it is very different from mechanical refrigeration ProductSiteLaunchDate : 2025-03-26T15:30:37.362Z Size : 1.45*1.45*1.67mm SupplierDeclaredDgHzRegulation : not_applicable UnspscCode : 30000000
