Improved mechanical and thermomechanical properties of alumina substrate via iron doping

We present a method to improve the overall properties of sintered alumina substrate via iron doping that has a higher fracture toughness, lower thermal conductivity, lower thermal expansion coefficient and comparable dielectric constant to pure alumina. Such properties are beneficial for harsh envir...
