A study of a non-destructive inspection system for hidden special nuclear materials in the cargo container at the sea port has been carried out under a promotion of Japan Science and Technology. This inspection system consists of an active neutron detection method for a fast screening purpose and a nuclear resonance fluorescence (NRF) method for isotope(More)
A detailed investigation on the control of residual stresses, especially gradient stress, in InP/air-gap structures is presented. Free standing cantilevers with stress compensation by Ga<sub>0.03</sub>In<sub>0.97</sub>P layers of various thicknesses and by a variation of V/III flux ratio in growth direction were fabricated, leading to controlled stress(More)
