摘要
Various transistors, such as field-effect transistors, and methods of fabricating the transistors are disclosed herein. An exemplary transistor includes a phosphorene-containing layer having a channel region, a source region, and a drain region defined therein. A passivation layer is disposed over the phosphorene-containing layer. A source contact and a drain contact extend through the passivation layer, such that the source contact and the drain contact are respectively coupled with the source region and the drain region. A gate stack is disposed over the channel region. In some embodiments, the gate stack includes a gate dielectric layer and a gate electrode layer, where the gate dielectric layer extends through the passivation layer and contacts the channel region. In some embodiments, the gate stack includes a gate electrode layer disposed over the passivation layer, and a portion of the passivation layer serves as a gate dielectric layer of the gate stack.
