QD floating gate NVRAM using QD channel for faster erasing [PDF]
A new pathway to design floating gate quantum dot (QD) non‐volatile RAM (QDNVRAM) cells that possess high‐speed low‐voltage Erase capabilities not possible with conventional floating gate NV memories is presented. This is achieved by directly accessing the QD floating gate layer with an additional drain (D2) during the Erase operation.

qd-Type Methods for Quasiseparable Matrices [PDF]
In the last few years many numerical techniques for computing eigenvalues of structured rank matrices have been proposed. Most of them are based on QR iterations since, in the symmetric case, the rank structure is preserved and high accuracy is guaranteed.

Investigation of carrier dynamics of QDs using kinetic model and ultrafast spectroscopy
The study of carrier dynamics of QDs is extremely important for developing efficient light-harvesting systems. Here, we investigate size-dependent hole transfer from CdSe QDs to 4-aminothiophenol (4-ATPh) ligand using ultrafast spectroscopy.
