Phys Rev Lett. 2013 Mar 08;110(10):107204. doi: 10.1103/PhysRevLett.110.107204. Epub 2013 Mar 07.

We investigate the two-dimensional highly spin-polarized electron accumulation layers commonly appearing near the surface of n-type polar semiconductors BiTeX (X=I, Br, and Cl) by angular-resolved photoemission spectroscopy. Because of the polarity and the strong spin-orbit interaction built in the...

BACKGROUND: For patients with reactivation of human cytomegalovirus (CMV), a highly sensitive and accurate CMV quantification system is essential to monitor viral load.METHODS: We constructed a real-time detection PCR (RTD-PCR) system for CMV DNA and evaluated its linearity, lower...

Design, implementation and characterization of a quantum-dot-based volumetric display.

Scientific reports

Hirayama R, Naruse M, Nakayama H, Tate N, Shiraki A, Kakue T, Shimobaba T, Ohtsu M, Ito T.
PMID: 25683656
Sci Rep. 2015 Feb 16;5:8472. doi: 10.1038/srep08472.

In this study, we propose and experimentally demonstrate a volumetric display system based on quantum dots (QDs) embedded in a polymer substrate. Unlike conventional volumetric displays, our system does not require electrical wiring; thus, the heretofore unavoidable issue of...
