Raman spectroscopy of active-carbon electrodes when Au colloids are placed at the electrolyte/electrode interface
H. Grebel, Y. Zhang
We use surface enhanced Raman spectroscopy (SERS) in studying functionalized Au nanoparticles (AuNPs) when incorporated in active-carbon (A-C) based super-capacitor cells. We obser…
Optically Controlled Supercapacitors with Semiconductor Embedded Active Carbon Electrodes
H. Grebel
Supercapacitors, S-C - capacitors that take advantage of the large capacitance at the interface between an electrode and an electrolyte - have found many short-term energy applicat…
The effect of periodic spatial perturbations on the emission rates of quantum dots near graphene platforms
X. Miao, D. J. Gosztola, X. Ma +3
Quenching of fluorescence (FL) at the vicinity of conductive surfaces, and in particular, near a 2-D graphene layer has become an important biochemical sensing tool. The quenching…
Graphene channels interfaced with an array of individual quantum dots
Xin Miao, Haim Grebel
Surface graphene guides were interfaced with an array of individual semiconductor quantum dots, whose position was commensurate with the optical guide modes. The surface guide serv…
Raman signal-enhancement and broadening with graphene-coated diamond-shape nano-antennas
Charilaos Paraskevaidis, Tevye Kuykendall, Mauro Melli +6
We used broad-band diamond-shape antennas, whose bandwidth could cover the frequency range between the pump laser and the scattered modes, in conjunction with uniformly deposited g…
Negative differential resistance with graphene channels, interfacing distributed quantum dots in Field-Effect Transistors
Samarth Trivedi, Haim Grebel
Field effect transistors with channels made of graphene layer(s) were explored. The graphene layer(s) contacted a distributed array of well-separated semiconductor quantum dots (QD…
