I'm a high school student, and I was researching about oxide semiconductors and TFTthin-film transistors when I found something confusing. Here's what I know: Normally, doping semiconductors causes the conductivity of the material. However, a large band gap requires more energy for an electron to move to the conduction band, resulting in less current, and making it harder for electrons to flow.

In oxide semiconductors, oxide materials are doped, but they have a large band gap of more than $3 \ \text{eV}$, and yet they have high conductivity. Something seems to be missing, and I'll be happy for any advice or points at misconceptions. Thank you!

Why do oxide semiconductors have a large bandgapband gap but high electric conductivity?

I'm a high school student, and I was researching about oxide semiconductors and TFT when I found something confusing. Here's what I know: Normally, doping semiconductors causes the conductivity of the material. However, a large band gap requires more energy for an electron to move to the conduction band, resulting in less current, and making it harder for electrons to flow.

In oxide semiconductors, oxide materials are doped, but they have a large band gap of more than 3eV$3 \ \text{eV}$, and yet they have high conductivity. Something seems to be missing, and I'll be happy for any advice or points at misconceptions. Thank you!
