The TEM in-situ thermoelectric system, Lightning, helps researchers observe the real-time dynamics of sample changes while precisely controlling the charging and heating environment.
The Nano-Chip in Lightning's sample bars utilizes a 4-point-probe method to accurately control voltage and temperature while acquiring meaningful data.
The unique design of the Nano-Chip allows the environmental conditions to be controlled individually or simultaneously to maximize voltage and temperature.
The ability to conduct experiments at high temperatures up to 1300°C and high voltages up to 150V, or to simultaneously deliver an electric field of 300kV/cm at 900°C, is the only product on the market that maximizes in situ environmental stimulation at high temperatures and high voltages.
The unique four-point heating method (4-point-probe method), as well as advanced technology and materials, maintains high reliability and stability at high temperatures and pressures. Even at temperatures up to 1000C (AT=1000C), the drift rate is less than 200 nm, and the sample stabilization time is short, so that high-quality imaging can be maintained over a long period of time.
Measure IVs with true DA current sensitivity while performing thermal studies, and with a resolution of up to 60 pm, obtain clear atomic images to help researchers better understand the structure and properties of materials.
The closed 4-point probe feedback loop provides maximum versatility, accuracy (95%) and temperature uniformity (99.5%) in controlling stimuli and measuring responses.
4 point probe method can be obtained at temperatures up to 1300°C and electric fields above 300 kV/cm at 900C. Detects currents in the range of 1pA-100mA and performs AC measurements up to 100Hz.
Less than 200 nm drift even at temperatures up to 1000C (AT=1000C), short sample stabilization times, and atomic resolution even at high voltages.
Closed 4-point probe feedback loop provides maximum versatility in controlling stimulus and measuring response with accuracy (≥95%) and uniformity (e99.5%).
Obtain temperatures up to 1300°C and electric fields above 300 kv/cm at 900C. Detects currents in the range of 1pA-100mA and performs AC measurements up to 100 H
With the unique SiNx window design, it is easy to place sample flakes or nanowires in the elongated window, or select the SiNx window to support nanoparticles.
Different configurations are available to suit your experimental needs. Choose from dedicated bias or heating chips and simultaneous bias + heating. Supports configuration upgrades during subsequent use, realizing diverse experimental designs.

“In operando TEM observations provide a unique opportunity to visualise the correlations between the electrical properties and the structural changes. The exceptional stability of the DENSsolutions holder allows the in operando TEM experiments to be performed with atomic resolution. Recently, we successfully observed structural changes of resistive switching and organic-inorganic metal-halide perovskite solar cells devices while under electrical stimulus inside a TEM”
