• The effect of relaxation oscillations in integrated optical comb demultiplexers based on injection locking 

  Shortiss, Kevin; Dernaika, Mohamad; Shayesteh, Maryam; Peters, Frank H. (Institute of Electrical and Electronics Engineers (IEEE), 2019-09-18)

  Narrowly spaced optical combs are being considered for use in future wavelength division multiplexing optical networks. Optical injection locking has been demonstrated as an effective method of demultiplexing these narrow ...
• Quantum confinement-induced semimetal-to-semiconductor evolution in large-area ultra-thin PtSe2 films grown at 400 °C 

  Ansari, Lida; Monaghan, Scott; McEvoy, Niall; Coileáin, Cormac Ó.; Cullen, Conor P.; Lin, Jun; Siris, Rita; Stimpel-Lindner, Tanja; Burke, Kevin F.; Mirabelli, Gioele; Duffy, Ray; Caruso, Enrico; Nagle, Roger E.; Duesberg, Georg S.; Hurley, Paul K.; Gity, Farzan (Nature Publishing Group, 2019-09-09)

  In this work, we present a comprehensive theoretical and experimental study of quantum confinement in layered platinum diselenide (PtSe2) films as a function of film thickness. Our electrical measurements, in combination ...
• Reconfigurable horizontal-vertical carrier transport in graphene/HfZrO field-effect transistors 

  Dragoman, Mircea; Modreanu, Mircea; Povey, Ian M.; Dinescu, Adrian; Dragoman, Daniela (IOP Publishing, 2019-09-26)

  We have fabricated at wafer level field-effect-transistors (FETs) having as channel graphene monolayers transferred on a HfZrO ferroelectric, grown by atomic layer deposition on a doped Si (100) substrate. These FETs display ...
• Overview of optical and electrochemical alkaline phosphatase (ALP) biosensors: recent approaches in cells culture techniques 

  Balbaied, Thanih; Moore, Eric (MDPI, 2019-08-23)

  Alkaline phosphatase (ALP), which catalyzes the dephosphorylation process of proteins, nucleic acids, and small molecules, can be found in a variety of tissues (intestine, liver, bone, kidney, and placenta) of almost all ...
• Acoustic deformation potentials of n -type PbTe from first principles 

  Murphy, Aoife R.; Murphy-Armando, Felipe; Fahy, Stephen; Savić, Ivana (American Physical Society, 2018-08-03)

  We calculate the uniaxial and dilatation acoustic deformation potentials Lu and Ld of the conduction band L valleys of PbTe from first principles, using the local density approximation (LDA) and hybrid functional (HSE03) ...
