Neutron reflectometry on Co-Cr layers [PDF]

open access: yes, 1993
Polarized neutron reflection experiments were performed on a thin in-plane magnetized Co-Cr layer deposited on a quartz substrate. Data taken at a low magnetic field ( 0.1 T) clearly indicate the existence of an initial layer at the substrate side ...

First results of a GNSS-R experiment from a stratospheric balloon over boreal forests [PDF]

open access: yes, 2015
The empirical results of a global navigation satellite systems reflectometry (GNSS-R) experiment onboard the Balloon EXperiments for University Students (BEXUS) 17 stratospheric balloon performed north of Sweden over boreal forests show that the power of

Photolyzable Polymer Brushes: Subtractive 3D Structuring of Surfaces Using Water and Light

open access: yesAngewandte Chemie, EarlyView.
Facile structuring of polymer brushes is achieved by flipping the process from controlled growth to controlled brush photolysis. Using surface‐initiated radical ring‐opening polymerization of cyclic monomers with photocleavable cyclobutane rings, photodegradable targets are embedded into the polymer chains. The enabled continuous subtractive patterning

Advancing Reflectometry [PDF]

open access: yesEos, Transactions American Geophysical Union, 2013
Reflectometry, a microwave remote‐sensing technique to extract geophysical data from scattered satellite transmissions, was first demonstrated using Global Navigation Satellite System (GNSS) reflections. Recently, reflectometry has been extended to the reutilization of digital communication satellite signals for Earth remote sensing, now referred to as

Radio-frequency reflectometry on an undoped AlGaAs/GaAs single electron transistor

open access: yes, 2014
Radio frequency reflectometry is demonstrated in a sub-micron undoped AlGaAs/GaAs device. Undoped single electron transistors (SETs) are attractive candidates to study single electron phenomena due to their charge stability and robust electronic ...

Single-shot readout of hole spins in Ge [PDF]

open access: yes, 2018
The strong atomistic spin orbit coupling of holes makes single-shot spin readout measurements difficult because it reduces the spin lifetimes. By integrating the charge sensor into a high bandwidth radio-frequency reflectometry setup we were able to ...
