Specific heat data in GaAs/AlGaAs at 5/2 filling fraction: 20201112 data set

Each data set name incorporates the date in which the data was acquired. There are a total of 6 data sets as shown in the table below (the current one, 20201112, is part of it). In each data set there is a series of txt files (current one has 30) that contain relevant information about the dataset such as the magnetic field (both relative B* and absolute values), the FQH state as well as a table with the raw data file names and the corresponding quantities of interest (input square wave DC offset + amplitude in Volts, set temperature in Kelvin, mean/uncertainty of/in temperature in Kelvin, signal samples - averaging, resistor values in Ohms, gain, frequency in Hertz, time stamp and time difference between each acquisition in seconds). The name of these information files is composed of the date in which the data set was acquired, the cooldown number, the sample name/number and the conductance (G) followed by the file number (increment of 1). Furthermore, each data set contains all the raw data save in txt files (current one has 570). The name of each file begins with Zurich (ZH) is followed be the cooldown number, the date in which the dataset was acquired, the row number of the data matrix (for each new thermal bath - dilution refrigerator temperature) and the column number of the data matrix (for each different input voltage - i.e. square wave DC offset + amplitude at the same thermal bath - dilution refrigerator temperature). Each raw data file contains 2 columns. The first column is the time in seconds. The second column is the voltage drop across the sensing 1 kilo Ohm resistor in Volts (which translates to current across the Corbino device). This is the raw response (to the bipolar square wave input) of the 2D electron gas (2DEG) measured by the Zurich digitizer.

每个数据集名称均包含数据采集日期。如表所示，共有6个数据集（当前数据集20201112为其中之一）。每个数据集包含一系列txt文件（当前数据集含30个），文件内记录数据集相关信息，包括磁场（相对值B*与绝对值）、分数量子霍尔态（FQH state），以及一个表格——表格列出原始数据文件名及对应的关注量（输入方波直流偏移量+振幅，单位为伏特（Volts）；设定温度，单位为开尔文（Kelvin）；温度的均值/不确定度，单位为开尔文（Kelvin）；信号样本（平均化）；电阻值，单位为欧姆（Ohms）；增益；频率，单位为赫兹（Hertz）；时间戳；以及每次采集的时间差，单位为秒）。这些信息文件的名称由数据集采集日期、冷却次数、样本名称/编号、电导（G）及文件编号（递增1）组成。此外，每个数据集包含所有存储于txt文件中的原始数据（当前数据集含570个文件）。每个原始数据文件名称以Zurich（ZH）开头，其后依次为冷却次数、数据集采集日期、数据矩阵行号（对应每个新热浴——稀释制冷机温度）及数据矩阵列号（对应每个不同输入电压——即同一热浴下的方波直流偏移量+振幅，热浴指稀释制冷机温度）。每个原始数据文件含2列：第一列为时间（单位为秒）；第二列为传感用1千欧姆电阻两端的电压降，单位为伏特（Volts）——该电压降对应科尔宾诺器件（Corbino device）中的电流。这是苏黎世数字化仪测量得到的二维电子气（2D electron gas）对方波输入的原始响应。待下载原始数据：ZH-20C1-1112-1-00000.txt至ZH-20C1-1112-30-00018.txt（共570个文件）。
