Meniscus-Assisted Technique Produces Perovskite PV Films
2017/7/24
A new low-temperature solution printing technique allows fabrication of high-efficiency perovskite solar cells with large crystals intended to minimize current-robbing grain boundaries. The meniscus-a...
Photon-induced carrier transport in high efficiency midinfrared quantum cascade lasers
Photon-induced carrier transport midinfrared quantum cascade lasers Optics
2011/8/18
Abstract: A midinfrared quantum cascade laser with high wall-plug efficiency is analyzed by means of an ensemble Monte Carlo method. Both the carrier transport and the cavity field dynamics are includ...
High efficiency tomographic reconstruction of quantum states by quantum nondemolition measurements
High efficiency tomographic reconstruction of quantum states quantum nondemolition measurements
2010/10/20
We propose a high efficiency tomographic scheme to reconstruct an unknown quantum state of the qubits by using a series of quantum nondemolition (QND) measurements. The proposed QND measurements of th...
