Nonlinear transport in Venturi-Shaped 2D Systems

Table 1. Measured voltage data for a single quantum well with a symmetric channel This table contains measured longitudinal voltage values ((V_{xx})) for a single quantum well with a symmetric channel under different DC current and temperature conditions. The measurements were performed using: (V_{ac} = 0.1 , \text{V} \times 2) (R_{load} = 100 , \text{k}\Omega) From these values: (I_{ac} = 2 \times 10^{-6} , \text{A}) (R_{xx} = \dfrac{V_{xx}}{I_{ac}}) The DC current is calculated as: (I_{dc} = \dfrac{V_{dc} \times 2}{R_{load}}) In general, resistance is calculated using: (R = \dfrac{V}{I}) where (R) is resistance, (V) is voltage, and (I) is current. The data are provided in CSV format with the following structure: The first row lists (V_{dc}) values in volts (V). The first column lists temperature values in kelvin (K). The remaining cells contain the measured voltage values ((V)) corresponding to each combination of (V_{dc}) and temperature. A small technical correction: the data cells correspond to each temperature row and (V_{dc}) column. Table 2. Measured voltage data for a single quantum well with Venturi geometry This table contains measured longitudinal voltage values for a single quantum well with Venturi geometry under varying DC bias and temperature conditions. The measurements are organized in a CSV-compatible tabular format. In this table: The first column lists (V_{dc}) values in volts (V). The first row lists temperature conditions in kelvin (K). The remaining cells contain the measured voltage values ((V)) corresponding to each combination of (V_{dc}) and temperature. The dataset can be used to calculate resistance from the measured voltage and current using: [R = \frac{V}{I}] where (R) is resistance, (V) is voltage, and (I) is current. For consistency with the other tables, the DC current may be derived from the applied DC voltage and load resistance using: [I_{dc} = \frac{2V_{dc}}{R_{load}}] and the longitudinal resistance may be calculated from the measured voltage values once the AC excitation current is known. One note from the sheet itself: the first temperature-related header appears as “V32(T=10K)”, while the remaining top-row headers are numeric temperature values. For Zenodo, it may be worth normalizing that header so all temperature columns use the same style. Table 3. Measured voltage data for a bilayer sample with symmetric channel This table contains measured longitudinal voltage values for a bilayer sample with a symmetric channel under varying DC voltage bias and temperature conditions. The data are arranged in a CSV-compatible tabular format as follows: The first column lists (V_{dc}) values in volts (V). The first row lists temperature values in kelvin (K). The remaining cells contain the measured voltage values ((V)) corresponding to each combination of (V_{dc}) and temperature. These measurements can be used to calculate resistance using the standard relation [R = \frac{V}{I}] where (R) is resistance, (V) is voltage, and (I) is current. If the same measurement setup is used as in the other tables, the DC current can be estimated from [I_{dc} = \frac{2V_{dc}}{R_{load}}] and the longitudinal resistance can be derived from the measured voltage values once the AC excitation current is known. Table 4.

The data are arranged in a CSV-compatible tabular format as follows: The first column lists (V_{dc}) values in volts (V). The first row lists temperature values in kelvin (K). The remaining cells contain the measured voltage values ((V)) corresponding to each combination of (V_{dc}) and temperature. These measurements can be used to calculate resistance using the relation [R = \frac{V}{I}] where (R) is resistance, (V) is voltage, and (I) is current. If the same measurement setup is used as in the other datasets, the DC current can be estimated from [I_{dc} = \frac{2V_{dc}}{R_{load}}] and the longitudinal resistance can be derived from the measured voltage values once the AC excitation current is known.
