EBL Absorption Signatures in DC2 Data

EBL Absorption Signatures in DC2 Data. Jennifer Carson (SLAC) DC2 closeout meeting June 1, 2006. Motivation. How well can we measure EBL absorption in 55 days of data? How sure can we be that we are distinguishing intrinsic spectral breaks from absorption signatures?

How to improve Learning Disabilities in Children, NJ?

A learning disability (LD) is the most frequent problem for which children are enrolled in special education classes. LD means a child has specific difficulties in obtaining information, often leading to deficiencies in educational skills. Distinguishing an LD from other disabilities - or a motivational problem - can be difficult, so misunderstandings are common.

CONCLUSION

CONCLUSION. W e investigated the effect of the p - AlGaN EBL on efficiency droop in InGaN / GaN MQW LEDs. At low current density, LEDs with an EBL show a higher EQE than LEDs without an EBL. However, LEDs without an EBL show a higher EQE at high current density.
