I'm trying to simulate TFET by Sentaurus TCAD, and I have specified the parameter of tunneling in the material parameter file as follow:

Material = "SiO2"{

BarrierTunneling{

mt=0.36, 0.38

}

}

But the following error always appear:" Tunneling mass for interface coupled to a trap by BarrierTunneling is not specified.!"

How I could solve these error???

Thanks
