As fabricated, the phosphorene MOSFET was stable in atmosphere for at least 100 h. With annealing at 200{\\deg}C in dry nitrogen for 1 h, its drain current increased by an order of magnitude to approximately 100 mA/mm, which could be attributed to the reduction of trapped charge in Al2O3 and/or Schottky barrier at the source and drain contacts. Thereafter, the drain current was stable between -50{\\deg}C and 150{\\deg}C up to at least 1000 h.
