High carrier mobility in transparent Ba1−xLaxSnO3 crystals with a wide band gap
High carrier mobility in transparent Ba1−xLaxSnO3 crystals with a wide band gap
We discovered that perovskite (Ba,La)SnO3 can have excellent carrier mobility even though its band gap is large. The Hall mobility of Ba0.98La0.02SnO3 crystals with the n-type carrier concentration of \sim 8-10\times10 19 cm-3 is found to be \sim 103 cm2 V-1s-1 at room temperature, and the precise measurement of the …
