Photoelectron spectroscopy study of band alignment at interface between Ni-InGaAs and In0.53Ga0.47As. Applied Physics Letters 99 (1) : -. ScholarBank@NUS Repository. https://doi.org/10.1063/1.3607959 | Abstract: | The work function of Ni-InGaAs and the band alignment between Ni-InGaAs and In0.53Ga0.47As were investigated using photoelectron spectroscopy. The vacuum work function of Ni-InGaAs is obtained to be ∼5.1 eV using ultraviolet photoelectron spectroscopy (UPS). In addition, it was observed that the Fermi level of Ni-InGaAs is aligned to near conduction band of In0.53Ga0.47As at interface. For Ni-InGaAs formed on p-type In0.53Ga0.47As, this gives a Schottky contact with a hole barrier height of 0.8 ± 0.1 eV. Ni-InGaAs would form an ohmic contact on n-type In0.53Ga0.47As. © 2011 American Institute of Physics. | Source Title: | Applied Physics Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/82896 | ISSN: | 00036951 | DOI: | 10.1063/1.3607959 |
