Millimeter wave absorption by confined acoustic modes in CdSe/CdTe core-shell quantum dots

2007

International audience; Taking advantage of the specific core-shell charge separation structure in the CdSe/CdTe core-shell Type-II quantum dots (QDs), we experimentally observed the resonant-enhanced dipolar interaction between millimeter-wave (MMW) photons and their corresponding (l = 1) confined acoustic phonons. With proper choice of size, the absorption band can be tuned to desired frequency of MMW imaging. Exploiting this characteristic absorption, in a fiber-scanned MMW imaging system, we demonstrated the feasibility of CdSe/CdTe QDs as the contrast agents of MMW imaging.

Sharing of Na+ by Three −COO– Groups at Deprotonated Carboxyl-Terminated Self-Assembled Monolayer-Charged Aqueous Interface

2018

By combining theoretical calculations and experimental observations, we show that Na+ can be shared by three charged −COO– groups of the deprotonated carboxyl-terminated self-assembled monolayers i...
