Crystal field analysis of Dy and Tm implanted silicon for photonic and quantum technologies (2014)
Journal Article
silicon for photonic and quantum technologies. Optics express, 22(24), 29292-29303. https://doi.org/10.1364/OE.22.029292

We report the lattice site and symmetry of optically active Dy3+ and Tm3+ implanted Si. Local symmetry was determined by fitting crystal field parameters (CFPs), corresponding to various common symmetries, to the ground state splitting determined...

n-type chalcogenides by ion implantation (2014)
Journal Article
Hughes, M., Fedorenko, Y., Gholipour, B., Yao, J., Lee, T., Gwilliam, R., …Curry, R. (2014). n-type chalcogenides by ion implantation. Nature communications, 5, 5346. https://doi.org/10.1038/ncomms6346

Carrier-type reversal to enable the formation of semiconductor p-n junctions is a prerequisite for many electronic applications. Chalcogenide glasses are p-type semiconductors and their applications have been limited by the extraordinary difficulty... Read More about n-type chalcogenides by ion implantation.

Electroluminescence from an electrostatically doped carbon nanotube field-effect transistor (2014)
Journal Article
carbon nanotube field-effect transistor. Nanoscience and Nanotechnology Letters, 6(10), 881-886. https://doi.org/10.1166/nnl.2014.1831

We report electroluminescence (EL) from a carbon nanotube field-effect transistor with split-gates. EL is generated by the electrostatic doping technique. Six EL bands could be observed, with the strongest band peaking between 0.867 and 0.850 eV wi...

Ion-implantation-enhanced chalcogenide-glass resistive-switching devices (2014)
Journal Article
Hughes, M., Fedorenko, Y., Gwilliam, G., Homewood, K., Hinder, S., Gholipour, B., …Curry, R. (2014). Ion-implantation-enhanced chalcogenide-glass resistive-switching devices. Applied Physics Letters, 105, 083506. https://doi.org/10.1063/1.4894245

We report amorphous GaLaSO-based resistive switching devices, with and without Pb-implantation before deposition of an Al active electrode, which switch due to deposition and dissolution of Al metal filaments. The devices set at 2–3 and 3–4V with r... Read More about Ion-implantation-enhanced chalcogenide-glass resistive-switching devices.

Photocurrent from a carbon nanotube diode with splitgate and asymmetric contact geometry (2014)
Journal Article
and asymmetric contact geometry. Materials Research Express, 1(2), 026304. https://doi.org/10.1088/2053-1591/1/2/026304

We fabricated a Ti/Pd asymmetrically contacted single carbon nanotube (CNT) field-effect transistor (FET) with split-gates. Transfer characteristics can be explained if the Schottky barrier for electrons is lower at the Pd contact than it is at th...

Waveguides in Ni-doped glass and glass–ceramic written with a 1 kHz femtosecond laser (2014)
Journal Article
femtosecond laser. Optical Materials, 36(6), 1604-1608. https://doi.org/10.1016/j.optmat.2014.04.042

We report waveguides in Ni-doped Li2O–Ga2O3–SiO2 (Ni:LGS) glass and glass–ceramic (GC) fabricated with a femtosecond (fs) laser with repetition rate of 1 kHz. When the glass is annealed to form a GC, the waveguides are erased. However, in the GC th... Read More about Waveguides in Ni-doped glass and glass–ceramic written with a 1 kHz femtosecond laser.

Split gate and asymmetric contact carbon nanotube optical devices (2014)
Journal Article

Asymmetric contacts or split gate geometries can be used to obtain rectification, electroluminescence (EL) and photocurrent from carbon nanotube field effect transistors. Here, we report devices with both split gates and asymmetric contacts and show... Read More about Split gate and asymmetric contact carbon nanotube optical devices.
