Transport property analysis method for thermoelectric materials: material quality factor and the effective mass model [PDF]
, 2017 Thermoelectric semiconducting materials are often evaluated by their figure-of-merit, zT. However, by using zT as the metric for showing improvements, it is not immediately clear whether the improvement is from an enhancement of the inherent material ...

Advanced Materials, EarlyView.Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

Thermoelectric properties of Si-based thermoelectrics
Journal of Advanced Science, 1999 The thermal conductivity κ and the electric properties of Si1-xGex (x≤0.03) samples doped with Group 3B and 5B elements which were prepared by arc melting were measured as functions of carrier (or dopant) concentration n and of temperature in the range from 298K to 1273K.
