FIG. 1.

Average distance between -doping frontier and anode as a function of time for devices operated at different temperatures under 200-V bias. The solid lines are linear fits to the data. All devices have an anode-to-cathode spacing of 2.0 mm. The inset shows the logarithmic -doping propagation rate vs inverse temperature. The dashed line represents an exponential fit to the data.

FIG. 2.

Doping propagation rate vs applied voltage bias for devices operated at a fixed temperature of 320 K. All devices have an anode-to-cathode spacing of 2.0 mm. The solid line represents a linear fit to the data.

FIG. 3.

Time evolution of doping profile of 2-mm planar LECs. (a) Doping profile at 200 K. (b) Doping profile at 200 K after 98 h while under a voltage bias of 200 V. (c) Doping profile of a formed junction at 200 K. (d) Doping profile at 200 K after 98 h while under a voltage bias of 200 V. (e) Doping profile of a planar LEC under 200 V at 325 K. (f) Doping profile after 5 min under 200 V at 325 K.
