Diffusion-related lifetime of indirect excitons in diamond
K. Konishi, I. Akimoto, J. Isberg +1
We investigate the lifetime of indirect excitons in extremely high purity diamond grown by the chemical vapor deposition method. A clear correlation is found between the lifetime a…
Improving electric power generation of a standalone wave energy converter via optimal electric load control
LiGuo Wang, MaoFeng Lin, Elisabetta Tedeschi +2
This paper aims to investigate electric dynamics and improve electric power generation of an isolated wave energy converter that uses a linear permanent magnet generator as the pow…
A valleytronic diamond transistor: electrostatic control of valley-currents and charge state manipulation of NV centers
Nattakarn Suntornwipat, Saman Majdi, Markus Gabrysch +5
The valley degree of freedom in many-valley semiconductors provides a new paradigm for storing and processing information in valleytronic and quantum-computing applications. Achiev…
Observation of transferred-electron oscillations in diamond
Nattakarn Suntornwipat, Saman Majdi, Markus Gabrysch +2
The transferred-electron oscillator (TEO) is a device used in microwave applications that utilizes the negative differential mobility (NDM) effect to generate continuous oscillatio…
Stability of Polarized States for Diamond Valleytronics
Johan Hammersberg, Saman Majdi, Kiran Kumar Kovi +4
The stability of valley polarized electron states is crucial for the development of valleytronics. A long relaxation time of the valley polarization is required to enable operation…
Silicon Oxide Passivation of Single-Crystalline CVD Diamond Evaluated by the Time-of-Flight Technique
Kiran Kumar Kovi, Saman Majdi, Markus Gabrysch +1
The excellent material properties of diamond make it highly desirable for many extreme electronic applications that are out of reach of conventional electronic materials. For comme…
Classical and Quantized Tensionless Strings
J. Isberg, U. Lindström, B. Sundborg +1
{}From the ordinary tensile string we derive a geometric action for the tensionless () string and discuss its symmetries and field equations. The Weyl symmetry of the usual st…
Space-Time Symmetries of Quantized Tensionless Strings
J. Isberg, U. Lindström, B. Sundborg
The tensionless limit of the free bosonic string is space-time conformally symmetric classically. Requiring invariance of the quantum theory in the light cone gauge tests the repar…
