Notizen: We studied the effect of threading dislocation scattering on the mobility of a two-dimensional electron gas. To verify our theory, we grew Si-doped AlGaAs/GaAs selectively doped heterostructures with different dislocation densities by changing the number of thermal annealing cycles. The theory agreed well with our experimental results. Previous work on high electron mobility transistors (HEMTs) fabricated on Si indicated that the device characteristics are insensitive to the dislocation density. Our theory states that the room temperature mobility reduction by dislocations with a density below 108 cm−3 does not affect HEMT device performance, which is consistent with empirically known results.

Notizen: Abstract It is suggested that weak coupling picture for theα-cluster states holds not only in the44Ti∼40Ca region but also in the upper part of thesd-shell region. To confirm this experimentally, theα-clustering aspects of38Ar is investigated.

Notizen: Abstract In the (6Li,d) reaction on36Ar, the strongly excited seventeen levels were observed at excitation energies above 11 MeV in40Ca. On the basis of the result of the DWBA analysis, these levels may correspond to the members of the higher nodal α-clusterK n =O+ band with prinicpal quantum numberN=14.
