1 At high photocurrent conditions, the presence of gas bubbles was observed on the surfaces of the Pt electrodes.

2 The application of photocurrent spectroscopy as a means to study thin oxide film on metals is reviewed. A description of the theoretical background and the experimental techniques is given.

3 The model describes the relationship between photocurrent and incident optical power, and it also illustrates the impact of the reverse bias to the variation of the junction capacitance.

4 A laser scanning electrochemical micro region photocurrent spectrum measurement system was developed.

5 The calculated positions of several photocurrent peaks are in good agreement with the experimental results.

6 However, the measured photocurrent results are similar at low applied voltages.

7 The dependence of the photocurrent on bias voltage is measured in this mode. Voltage step width, laser intensity and spot size are user adjustable.

8 We find that the photocurrent of this device is not reduced by the additional MQWs but the dark current is.

9 Based on the theory analysis of photocurrent distribution in the base region of color sensor,[www.Sentencedict.com] it can be found that the impurity concentration and the junction depth arc the main factors.

10 The new circuit directly digitizes the photocurrent of laser gyro successfully, and meets the need of high precision cavity length control system of laser gyro.

11 Experiment using discrete bipolar transistors has been performed to verify the effect of the photocurrent compensation method.

12 Figure 8 shows the influence of light power intensity on the photocurrent values.

13 Nevertheless, our results showed after the film was principally formed, photocurrent is proportional to film thickness.

14 Transient radiation response for microcircuit PN junctions with enhanced photocurrent models are calculated using two-dimensional numerical simulation.

15 Before this period, there is a positive deviation of photocurrent and the linear relationship does not hold.

16 Experiments were done to probe into the characteristics of APD. The relationships between avalanche voltage, dark current, photocurrent, NEP and temperature were educed separately.

17 The preamplifier-subtracter and expiation parts was used to counteract the variational photocurrent because the photoelectricity element array respond the light signal.

18 With only normal room light incident upon the LED there is insufficient photocurrent to discharge the capacitance below the threshold during the 100 microsecond receive period.

19 Finally, this paper analyzed and discussed the testing method of three electrodes, feature of the new LAPS and the infections of conductance of waiting testing electrolyte on photocurrent.

20 The amplifier input is a voltage proportional to the photocurrent signal produced by a photodiode, which is irradiated by a modulated light beam at the same chopper frequency.

21 In the case of anatase, higher light powers generated higher photocurrent values at high applied voltages.
