In this paper, we present electrically pumped GaAsBi quantum well (QW) laser diodes (LDs) grown by molecular beam epitaxy. The LDs reveal a record long lasing wavelength of 1.14 µm at 300 K and can be operated under CW excitation up to 273 K. They also show high performance with an internal quantum efficiency of 86% and an internal optical loss of 10 cm−1. The characteristic temperature is 79 K in...
Summary form only given as follows. Sterilization of foodstuffs by microwave plasma may be an efficient, environmental-friendly method, but the plasma needed cannot be attained easily. With the proprietary cavity of atmospheric microwave plasma called APMPS+JET, we have been able to gain the atmospheric microwave plasma of the gas mixture (air and argon), by which the teliospores of Tilletiacontroversa...
