Effects of partial hydrogenation on electronic transport properties in C60 molecular devices

► The transport properties can be modulated by partial hydrogenation. ► The transport properties of C60 molecular devices depend on the absorptions site. ► At low biases, the imbalance H-adsorption can enhance the electron transport. ► At low biases, the balance H-adsorption can suppress the electron transport. ► Negative differential resistance behavior can be observed in the case of pristine.
