Limit Laws for Consensus Protocols on the Complete Graph
Julian Becker, Konstantinos Panagiotou
We study a distributed consensus problem on a complete communication network of vertices, each holding one of two opinions. The vertices communicate in rounds, possibly in the…
Improved Universal Graphs for Trees
Julian Becker, Konstantinos Panagiotou, Matija Pasch
A graph is universal for a class of graphs , if, up to isomorphism, contains every graph in as a subgraph. In 1978, Chung and Graham asked for th…
Characterization of Chromium Compensated GaAs as an x-ray Sensor Material for Charge-Integrating Pixel Array Detectors
Julian Becker, Mark W. Tate, Katherine S. Shanks +5
We studied the properties of chromium compensated GaAs when coupled to charge integrating ASICs as a function of detector temperature, applied bias and x-ray tube energy. The mater…
The single photon sensitivity of the Adaptive Gain Integrating Pixel Detector
Julian Becker, Dominic Greiffenberg, Ulrich Trunk +6
Single photon sensitivity is an important property of certain detection systems. This work investigated the single photon sensitivity of the Adaptive Gain Integrating Pixel Detecto…
Properties of a radiation-induced charge multiplication region in epitaxial silicon diodes
Jörn Lange, Julian Becker, Eckhart Fretwurst +2
Charge multiplication (CM) in pn epitaxial silicon pad diodes of 75, 100 and 150 $\upmu$m thickness at high voltages after proton irradiation with 1 MeV neutron equivalent flue…
Measurements of charge carrier mobilities and drift velocity saturation in bulk silicon of <111> and <100> crystal orientation at high electric fields
Julian Becker, Eckhart Fretwurst, Robert Klanner
The mobility of electrons and holes in silicon depends on many parameters. Two of them are the electric field and the temperature. It has been observed previously that the mobility…
