Gain Modulation by Graphene Plasmons in Aperiodic Lattice Lasers
S. Chakraborty, O. P. Marshall, T. G. Folland +3
Two-dimensional graphene plasmon-based technologies will enable the development of fast, compact and inexpensive active photonic elements because, unlike plasmons in other material…
Modeling electric field sensitive scanning probe measurements for a tip of arbitrary shape
I. Kuljanishvili, Subhasish Chakraborty, I . J. Maasilta +2
We present a numerical method to model electric field sensitive scanning probe microscopy measurements which allows for a tip of arbtrary shape and invokes image charges to exactly…
Tunneling images of a 2D electron system in a quantizing magnetic field
I. J. Maasilta, Subhasish Chakraborty, I. Kuljanishvili +2
We have applied a scanning probe method, Subsurface Charge Accumulation (SCA) imaging, to resolve the local structure of the interior of a semiconductor two-dimensional electron sy…
Direct observation of micron-scale ordered structure in a two-dimensional electron system
I. J. Maasilta, Subhasish Chakraborty, I. Kuljanishvili +2
We have applied a novel scanned probe method to directly resolve the interior structure of a GaAs/AlGaAs two-dimensional electron system in a tunneling geometry. We find that the a…
