We demonstrate In0.53Ga0.47As surface channel MOSFETs using a gate-last process and MBE source/drain (S/D) regrowth. The structure uses a sacrificial N+ InGaAs channel cap layer between the regrown S/D contact layer and the channel, which is removed in the channel region by a “digital” etch process incorporating UV ozone oxidation and surface stripping in dilute HCl. A device with 65 nm-Lg and 1.2 nm EOT shows 1.6 mS/μm peak transconductance at Vds = 0.5 V and 120 mV/dec SS at Vds = 0.05 V, while 535 nm-Lg devices show 95 mV/dec SS at at Vds = 0.1 V.

In this paper, we report on high frequency performances of AlSb/InAs high electron mobility transistor (HEMT) with 120nm gate length at room temperature. The excellent combined cut-off frequencies fT/fmax of 290/335 GHz simultaneously obtained at drain bias of 0.36V is another demonstration of the ability of AlSb/InAs HEMT for high frequency operation with low-power consumption. Small-signal equivalent circuit parameters have been extracted.

Photon-correlation function g(2)(τ) of a single `doublecapped' InAs/InP quantum dot (QD) was obtained with high accuracy using a superconducting single-photon detector (SSPD). By using resonant excitation to the e1h0 state in the single InAs/InP QD, g(2)(0) was decreased to the detection limit. Rabi oscillation of the PL intensity of e0h0 state is also observed under the resonant excitation into the e1h0 state. These results suggest that the coherent exciton generation into e1h0 state is effective to improve the purity of the single-photon emission.

This paper describes the impact of a GaAs spacer inserted between the InP emitter and GaAsSb base of InP/GaAsSb/InP double-heterojunction bipolar transistors (DHBTs) grown by metalorganic chemical vapor deposition. The GaAs spacer suppresses the incorporation of excess Sb atoms from the GaAsSb base into the InP emitter, which reduces the recombination current at the junction. The fabricated DHBTs with a 0.5-μm-wide emitter show dc current gain of over 90 at current density (JC) of 10 mA/μm2. The 0.25-μm-emitter DHBTs yield current-gain cut-off frequency (ft) of 384 GHz and maximum oscillation frequency (fmax) of 264 GHz at JC of 14 mA/μm2.

In the work, a novel approach in fabricating high-performance of InAs/AlSb high electron mobility transistors using iridium (Ir) gate technology was proposed and investigated. The Ir-gate exhibited a superior metal work function which was beneficial for increasing Schottky barrier height (ØB) of InAs/AlSb heterostructure from 0.54 to 0.58 eV. The Ir-gate InAs/AlSb HEMT exhibited a Vth of -0.9 V, a maximum drain current of 270 mA/mm, and a peak transconductance of 420 mS/mm. In contrast, the Vth of Ti-gate InAs/AlSb HEMT was - 1.5 V, a maximum drain current of 257mA/mm, and a peak transconductance of 280mS /mm, respectively. It was suggested that Ir interface presented a high potential for high power transistor applications.

On-chip optical interconnections have potential for replace global copper wires on LSI chips. I n this work, as an integration method, an OMVPE butt-joint regrowth of 175-nm thick GaInAsP/InP was conducted toward an integration of active and passive components. In the numerical calculation, a coupling efficiency and residual reflection of designed butt-joint coupling were estimated to be 98% and -40 dB, respectively. In the experimental method, we investigated the dependence of butt-joint interface morphology and regrown surface flatness on the side etch depth and the mesa angle. As a result, a flat regrown surface without degradation in crystalline quality was obtained.

In this paper we present a very compact 0.28 × 0.55 mm2 six-stage terahertz monolithic integrated circuit (TMIC) using 35 nm gate length metamorphic high electron mobility transistors (mHEMTs). A linear gain of 20.3 dB at 610 GHz and more than 18 dB over the bandwidth from 557 to 616 GHz was achieved for a drain voltage Vd of only 0.6 V. The noise performance of the 35 nm mHEMT was investigated on the basis of a packaged H-band amplifier which achieved a small-signal gain of more than 20 dB between 220 and 300 GHz. The averaged measured noise figure was 6.1 dB which is to our knowledge the lowest published value of any MMIC technology in this frequency range. To determine the transistor reliability accelerated lifetime tests in air were done. Based on a 20 % gm_max degradation failure criterion a median time to failure of 1.8 × 105 h at a channel temperature of 75°C and VDS = 0.8 V was extrapolated

The structural properties of (In,Ga)As/GaP quantum dots (QDs) are studied by plane view and cross scanning tunneling microscopy. Time-resolved and pressure dependent photoluminescence experiments show a ground optical transition of indirect type. Mixed k.p/tight-binding simulations indicate a possible indirect to direct crossover depending on indium content and QD size. The incorporation of nitrogen in QDs is finally shown.
