    • Controlled Tuning of Whispering Gallery Modes of GaN/InGaN Microdisk Cavities 

      Aharonovich, Igor; Niu, Nan; Rol, Fabian; Russell, Kasey Joe; Woolf, Alexander J; El-Ella, Haitham A.R.; Kappers, Menno J.; Hu, Evelyn (American Institute of Physics, 2011)
      Controlled tuning of the whispering gallery modes of GaN/InGaN microdisk cavities is demonstrated. The whispering gallery mode (WGM) tuning is achieved at room temperature by immersing the microdisks in water and irradiating ...
    • Dislocation Density-Dependent Quality Factors in InGaN Quantum Dot Containing Microdisks 

      El-Ella, H.A.R.; Rol, F; Kappers, M.J.; Russell, Kasey Joe; Hu, Evelyn; Oliver, R.A. (American Institute of Physics, 2011)
      Microdisks incorporating InGaN quantum dots were fabricated using SiO2 microspheres as a hard mask in conjunction with a photoelectrochemical etch step from a structure containing a sacrificial InGaN/InGaN superlattice. ...
    • Effects of Forming Gas Anneal on Ultrathin InGaAs Nanowire Metal-Oxide-Semiconductor Field-Effect Transistors 

      Si, Mengwei; Gu, Jiangjiang J.; Wang, Xinwei; Shao, Jiayi; Li, Xuefei; Manfra, Michael J.; Gordon, Roy Gerald; Ye, Peide D. (American Institute of Physics, 2013)
      InGaAs gate-all-around metal-oxide-semiconductor field-effect transistors (MOSFETs) with 6 nm nanowire thickness have been experimentally demonstrated at sub-80 nm channel length. The effects of forming gas anneal (FGA) ...
    • Enhancing the Efficiency of SnS Solar Cells bia Band-Offset Engineering with a Zinc Oxysulfide Buffer Layer 

      Sinsermsuksakul, Prasert; Hartman, Katy; Kim, Sang Bok; Sun, Leizhi; Park, Helen Hejin; Chakraborty, Rupak; Buonassisi, Tonio; Gordon, Roy Gerald (American Institute of Physics, 2013)
      SnS is a promising earth-abundant material for photovoltaic applications. Heterojuction solar cells were made by vapor deposition of p-type tin(II) sulfide, SnS, and n-type zinc oxysulfide, Zn(O,S), using a device structure ...
    • III-V 4D Transistors 

      Gu, J.J.; Wang, Xinwei; Shao, J.; Neal, A.T.; Manfra, M.J.; Gordon, Roy Gerald; Ye, P.D. (Institute of Electrical and Electronics Engineers, 2012)
      We fabricated for the first time vertically and laterally integrated III-V 4D transistors. III-V gate-all-around (GAA) nanowire MOSFETs with \(3×4\) arrays show high drive current of \(1.35mA/ \mu m\) and high transconductance ...
