Journal ArticleDOI
Phase sensitive monitoring of electron bunch form and arrival time in superconducting linear accelerators
Caglar Kaya,Ch. Schneider,A. Al-Shemmary,W. Seidel,Michael Kuntzsch,Jayeeta Bhattacharyya,Martin Mittendorff,Pavel Evtushenko,S. Winnerl,G. Staats,Manfred Helm,Nikola Stojanovic,Peter Michel,Michael Gensch +13 more
TL;DR: In this paper, a simple approach for monitoring electron bunch form and arrival time combining electro-optic sampling and phase and frequency sensitive signal detection is presented, which has high impact for the developments of the next generation of 4th generation x-ray light sources working with long pulse trains or continuous wave mode of operation.
Journal ArticleDOI
In-plane interdot carrier transfer in InAs/GaAs quantum dots
Jayeeta Bhattacharyya,Sabine Zybell,Stephan Winnerl,Manfred Helm,Mark Hopkinson,Luke R. Wilson,Harald Schneider +6 more
TL;DR: In this article, the authors investigated inplane carrier transfer in InAs/GaAs self-assembled quantum dots (QDs) and found that the redistribution of carriers into the neighbouring QDs is the dominant mechanism of carrier relaxation.
Journal ArticleDOI
Magnetic control of Coulomb scattering and terahertz transitions among excitons
Jayeeta Bhattacharyya,S. Zybell,S. Zybell,F. Eßer,F. Eßer,Manfred Helm,Manfred Helm,Harald Schneider,L. Schneebeli,C. N. Böttge,B. Breddermann,Mackillo Kira,Stephan W. Koch,Aaron Maxwell Andrews,Gottfried Strasser +14 more
TL;DR: In this paper, a microscopic theory is developed to analyze the results of time-resolved terahertz quenching studies of the magnetoexcitonic photoluminescence from GaAs/AlGaAs quantum wells.
Journal ArticleDOI
Study of exciton-polaron interaction in pentacene field effect transistors using high sensitive photocurrent measurements
Haripriya Kesavan,Subhamoy Sahoo,Sanjoy Jena,Prashanth Kumar Manda,Amogh Kumar Baranwal,Soumya Dutta,Jayeeta Bhattacharyya,Debdutta Ray +7 more
TL;DR: In this article, the enhancement of conduction in the organic field effect transistors on light illumination is studied using phase sensitive photocurrent measurements on pentacene FET transistors, and two models are proposed on the exciton dynamics in the presence of gate induced polarons in the transistor channel.
Journal ArticleDOI
Enhancing the efficiency of red TADF OLED by optimizing the guest-host matrix and charge balance engineering
TL;DR: In this article, the performance of organic light emitting diodes (OLEDs) fabricated with a near infra red thermally activated delayed fluorescence (TADF) molecule 7,10-Bis(4-(diphenylamino)phenyl)-2,3-dicyanopyrazino phenanthrene (TPA-DCPP) was investigated.
