摘要
在非化学计量学（MnSe）1 - se （Tm0.76Se）中，发现了由霍尔常数和热电功率测定的载流子符号相同的温度和浓度区域。在极化子模型中解释了热能和电声的温度依赖关系。在温度和浓度的变化中，发现了纵向和横向能斯特-埃廷斯豪森系数符号的变化。建立了能斯特-埃廷斯豪森系数随磁场中电声变化的温度关系的一致性。在耦合电子-空穴对模型中解释了热功率和能-埃汀肖森系数随温度的最大值，并对电子-空穴对的解离和耦合极化子的钉住进行了解释。
Effect of nonstoichiometry on the Hall effect, Nernst‒Ettingshausen effect, and electrosound in (MnSe)1‒х(Tm0.76Se)х manganese selenides
―In nonstoichiometric (MnSe)1‒х(Tm0.76Se)х manganese selenide, the temperature and concentration regions with the same sign of carriers determined from the Hall constant and thermoelectric power have been found. The correlation of the temperature dependences of the thermopower and electrosound has been explained within the polaron model. A change in the sign of the longitudinal and transverse Nernst‒Ettingshausen coefficients upon variation in temperature and concentration has been detected. The agree of the temperature dependences of the Nernst‒Ettingshausen coefficients with a change in the electrosound in a magnetic field has been established. The maxima of the thermopower and Nernst‒Ettingshausen coefficients versus temperature have been explained within the model of coupled electron‒hole pairs with dissociation of the pairs and pinning of coupled polarons.
