Here using the first-principles calculations, we systematically investigate the electronic, transport and optical properties of monolayer $\\alpha-$ and $\\beta-$GeSe, the latter of which was recently experimentally realized. We found that, monolayer $\\alpha-$GeSe is a semiconductor with direct band gap of 1.6 eV, and $\\beta-$GeSe displays indirect semiconductor with the gap of 2.47 eV, respectively.
