Abstract

We present the development of a near infrared image intensifier tube based on a Generation III configuration. The photocathode driving this tube is based on a negative-electron-affinity (NEA) InGaAs design. The surface and crystalline quality of the InGaAs active layer for this device is characterized by x-ray diffraction (XRD), micro-Raman spectroscopy, energy dispersive x-rays (EDX), and Auger spectroscopy. Room temperature and 77 K photoluminescence (PL) and transmission measurements indicate the near infrared responsivity (1.2 - 1.7 micrometers ) of the InGaAs active layer. Reflection mode measurements of the photoresponse (PR) in an ultra high vacuum environment produced white light sensitivities of 100 (mu) A/lumen and quantum efficiencies of approximately 1% for wavelengths of 1300 - 1600 nm at 300 K. Sealed image tubes were created, and early sealed tube results show low quantum efficiencies (approximately 0.1% 1550 nm) due to nonoptimized active layer thickness.
